MuseScore 2.0.3 app image crashes on Ubuntu 14.04

• Oct 23, 2016 - 18:07

Hi all,

MuseScore is indeed awesome. I composed my first music in it in minutes.
Could play it, and even change colours of the noteheads. Then I closed the program normally. But, alas, when I want to start it again, MuseScore crashes. Sometimes
before I can do anything, sometimes after I have done some editing.

I really hope that MuseScore has been stunned by my shatterring masterpiece.
But a gnawing doubt persists: Could it be a bug?

Hence this email.

Here are some relevant info:

  1. I have read the "Known incompatibilities" section of the handbook. As I can occasionally run MuseScore perfectly, they do not seem to apply.
  2. I am running Ubuntu 14.04 (gnome) on a HP netbook (Intel atom processor).
  3. MuseScore 2.0.3 (app image downloaded within last week).
  4. I run the program from commanline. Every time the program crashes it greets me with a message like this:
    $ ./MuseScore-2.0.3-i686.AppImage
    initScoreFonts 0xa1fc240
    /tmp/.mount_nGlA84/AppRun: line 18: 13516 Segmentation fault      (core dumped) "${APPDIR}/bin/mscore-portable" "$@"
  5. Following suggestions given for a similar bug report for an earlier version of MuseScore, I disabled the Start Center
    from Preferences (during one of the few sessions that would allow me to get that far).
  6. I tried to run MuseScore through gdb. As I step through it I get plenty of error messages like:
    Single stepping until exit from function main,
    which has no line number information.
    __GI_getenv (name=0x804d82c "XDG_CACHE_HOME") at getenv.c:35
    35	getenv.c: No such file or directory.


    __x86.get_pc_thunk.bx () at ../sysdeps/i386/i686/multiarch/strcat.S:55
    55	../sysdeps/i386/i686/multiarch/strcat.S: No such file or directory.


    __strlen_ia32 () at ../sysdeps/i386/i686/multiarch/../../i586/strlen.S:43
    43	../sysdeps/i386/i686/multiarch/../../i586/strlen.S: No such file or directory.

    Indeed, I get one such message for every step. I wonder how can MuseScore occasionally run successfully at all if so many things could not be found! Anyway finally I get to the crash:

    (gdb) continue
    process 13534 is executing new program: /bin/bash
    initScoreFonts 0x98eb840
    remove keysig c at tick 0
    /tmp/.mount_Rd0IWw/AppRun: line 18: 13567 Segmentation fault      (core dumped) "${APPDIR}/bin/mscore-portable" "$@"
    [Inferior 1 (process 13534) exited with code 0213]

    Can anybody please help me to convince myself that it is not a bug...just an devastating effect of my first composition.

    Thanks a lot for your time.



As suggested for a similar problem, I ran the command
./MuseScore-2.0.3-i686.AppImage check-depends > dep.txt
The resulting dep.txt is attached.
