MuseScore 2.0.2 in Ubuntu 14.04 (Trusty) crashes shortly after startup

• Sep 12, 2015 - 22:57

Hi all,

I've installed MuseScore 2.0.2 (revision 3543170) on my Ubuntu 14.04.3 LTS (Trusty) system, running
Linux kernel version 3.16.0-49-generic x86_64 and Qt library version 5.3.0. My machine is a Dell Inspiron laptop with a Intel Core i7-5500 CPU with 16 GB of RAM and a 1 TB hard disk with a 650 GB Linux partition. The install was made via apt-get using the Launchpad PPA ppa:mscore-ubuntu/mscore-stable, so it's supposed to be the latest stable version.

However, the program crashes after a few minutes of use without apparent reason, no matter which commands I use (if I don't do anything and just leave the program running, nothing happens). Running the program in debug mode shows only that the program terminates with a segmentation fault - there seems to be no abnormal debug messages before the segmentation fault.

Any help with this is appreciated. I'm trying to migrate from Sibelius to MuseScore and I have a lot of .sib scores exported to MusicXML I'd like to use / edit within MuseScore.


Comments

The problem could be due to a problem with the MusicXML generated by Sibelius then, or with how MuseScore imports it. If you can come up with a specific score and precise steps to reproduce the problem, that would be extremely helpful.

In reply to by Marc Sabatella

Hmm... Not really. The problem happens in the same way if I create a new score from scratch. All I do in this case is to create the score using the new score wizard. The score is created, OK, but after a while, no matter what I'm doing with it, the program crashes.

Sometimes, the program crashes even within a few seconds after startup, before I have the chance to do anything. This happens even if I start with the -F option to reset to factory settings. I don't know if it helps, but the first message appearing at the terminal when this happens and I start MuseScore using a shell command (no debug mode) looks like this:

/home/plaurids> musescore
initScoreFonts 0x304a6e0
init Help from:
cannot setup data for help engine: Cannot open collection file: /usr/share/mscore-2.0/manual/doc_pt_BR.qhc
Segmentation fault (core dumped)

Again, this also happens if I start the command in factory reset mode (-F option).

Curiously, I've just noticed my MuseScore installation didn't create a /manual folder under /usr/share/mscore-2.0 (which seems to explain the above message), so this might be related somehow to the crashing behavior. Any ideas?

In reply to by plaurids

Firstly, thank you for actually reading the handbook and trying some sensible solutions on your own before asking for help! Not everyone takes the time to do that...

The missing manuals are a known issue but shouldn't cause any problems. However, if you could try one of the new nightly builds for Ubuntu, these include the manuals so let me know if that solves it for you. If so I can try repackaging with the manual.

Also, do you have any other versions of MuseScore installed? Maybe one you compiled from source?

Finally, if 2.0.0 worked for you, you should be able to revert back to it using:

sudo apt-get remove musescore
sudo apt-get install musescore=2.0.0+dfsg1-0ubuntu~trusty1

(It might try to auto-update to 2.0.2 so see this AskUbuntu question for ways to stop that happening.)

Thanks for the tips shoogle,

Version 1.3 of MuseScore (which is the one currently installed by Ubuntu if I don't add the PPA) was actually working with no problems during the short time I used it. I decided to upgrade to 2.0.2 because there was a lot of missing features in 1.3, and my MusicXML files imported from Sibelius were sometimes badly scrambled when opened in MuseScore 1.3 (the flies were imported from Sibelius 7.0.2 for Mac running OSX Yosemite using the Dolet 6 plugin, which seems one of the best methods around). If I have to re-adjust almost every score element in a tens-of-pages long score, this kind of defeats the point of importing...

I haven't tried version 2.0.0 yet and I'm always a bit wary of using nightlies, but I'll try your two suggestions to see how they work out. I'll let you all know the results soon...

In reply to by plaurids

I don't think 1.3 is causing any problems. It should have been removed automatically when you upgraded.

You said you tried mscore -F already so there shouldn't be any preferences left over. However, I just remembered this bug report about a file not being deleted on a reset. Maybe try deleting the file manually and doing another reset?

It's good to be wary of nightlies in general, but they happen to be very stable at the moment. Just remember not to save anything that you open with the nightly or normal versions of MuseScore won't be able to read it.

In reply to by shoogle

Hi shoogle,

I don't believe it to be clutter left from version 1.3 either. I purged version 1.3 and deleted the .config/MuseScore folder manually, so there should be nothing left of it.

Purging 2.0.2, manually deleting the .config/MuseScore folder, reinstalling 2.0.2 and starting it with "musescore -F" via shell doesn't help either.

Moreover, the (latest?) nightly build

musescore-nightly_201509081531+REVISION.9878ef4~ubuntu14.04.1_amd64.deb

presented exactly the same behaviour as 2.0.2 (i.e. a segmentation fault within seconds after startup). It also still complains about the missing file /usr/share/mscore-nightly-2.1/manual/doc_pt_BR.qhc - the folder /manual is there, but the file doc_pt_BR.qhc indeed is still missing, as is any other file of the kind doc_(language).qhc. I don't believe this is causing the crashes either, though, after reading the links you've sent me.

I couldn't install 2.0.0 - apt-get says that version 2.0.0+dfsg1-0ubuntu~trusty1 is missing from the PPA:

/home/plaurids> apt-cache madison musescore
 musescore | 2.0.2+dfsg-1ubuntu1~trusty2 | http://ppa.launchpad.net/mscore-ubuntu/mscore-stable/ubuntu/ trusty/main amd64 Packages
 musescore | 1.3+dfsg-1 | http://archive.ubuntu.com/ubuntu/ trusty/universe amd64 Packages
 musescore | 1.3+dfsg-1 | http://archive.ubuntu.com/ubuntu/ trusty/universe Sources

Is there another PPA where I can get version 2.0.0? In the mean time, I've downgraded to 1.3, which is stable but a bit too limited for my purposes.

In reply to by plaurids

Interesting. I'm not sure what the problem is but I'll keep thinking.

In the meantime, 2.0.0 is available in the PPA, but perhaps it wont install via apt-get since it's not the most recent version. You can manually download and install it from this page: https://launchpad.net/~mscore-ubuntu/+archive/ubuntu/mscore-stable/+pac…

Click the arrow next to the package to expand it and download the DEB files called "musescore-common" and "musescore" (either 32bit or 64bit depending on your system). Make sure the stable PPA is in your list of sources and then double click on musescore-common to install it via Ubuntu Software Centre, then do the same with musescore. Finally, remove the stable PPA to prevent an automatic upgrade to 2.0.2.

In reply to by plaurids

This appears to be related to the Start Center. When I run musescore, the Start Center appears before the program crashes.

I have been able to work around this problem by specifying an existing score on the command-line to open (which bypasses the start center), and then disabling the start center in the Preferences.

I haven't been able to get a good backtrace for this crash, because my binary (installed from the Ubuntu PPA) lacks debug symbols.

In reply to by Ken Bloom

@Ken: hopefully Jojo's suggestion will fix it for you, but if you want to find the root cause of the issue then you could compile a debug version yourself.
https://musescore.org/en/developers-handbook/compilation/compile-instru…

You'll need to modify the build commands as follows:

make revision
make SUFFIX="-debug" LABEL="Debug Build" debug
sudo make SUFFIX="-debug" LABEL="Debug Build" installdebug

I'm reluctant to make the PPA nightlies debug builds because of the large executable size (~200MB compared to ~20MB for a non-debug build) and the fact that they auto-update.

Here's what I've got for a backtrace.

Thanks very much for this. There do seem to be lots of references to web components. I'm not familiar with that part of the code but hopefully this will mean something to somebody.

Did JoJo's suggestion of starting MuseScore with the -w option and then disabling the Start Centre in Preferences → General do anything for you?

Edit: our posts crossed. I see that -w worked but did you try disabling the Start Centre in preferences? Was it a permanent fix?

Ciao plaurids,
can you please try to run MuseScore inside gdb?
In this way you can obtain a stack trace which can be extremely useful since the debug mode is not showing anything interesting.
Steps:
1- Install MuseScore 2.0.2
2- Run in the terminal gdb mscore
3- Inside gdb run the instruction run -d
4- Reproduce the crash in MuseScore
5- Inside gdb run the instruction bt
6- Copy and paste the output of the backtrace in a post here.
From the backtrace we can hopefully identify what is going wrong.
Thank you for your collaboration.

Ciao,
ABL

Hello everybody!

I've also installed MuseScore 2.0.2 (revision f551dc11) on Linux Mint 17.1 (based on Ubuntu 14.04.3 LTS (Trusty) system), running Linux kernel version 3.16.0-49-generic x86_64 and Qt library version 5.3.0.

As I am experiencing exactly the same bug, (and found my meantime-solution in the same workaround), I hope I can help identifying what is going wrong, by fulfilling the request posted by Antonio BL.

So here is my output of the backtrace running and crashing MuseScore by opening the startcenter inside gdb:
