I've attached below a 0.9.6 Debian bug report that slipped through my radar (oh well... 0.9.6.2 seems to fix all the other bugs I've seen). Hopefully this can be sorted for 0.9.7 :)

It's from http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=591908
The terminal output is at http://bugs.debian.org/cgi-bin/bugreport.cgi?msg=5;filename=MuseScore.tx...
and you can get the MIDI file at http://www.classicalarchives.com/midi/composer/2239.html

I can reproduce the issue on 0.9.6.2 (but haven't rebuilt it with debugging symbols yet, so I don't have a backtrace, sorry).

Version: 0.9.6+dfsg-1
Severity: normal

Hi!

I am working on MIDI import of the Brahms Violin Concerto MIDI file that can
be downloaded for free from www.classicalarchives.com, into MuseScore.

When I open it within MuseScore, I get a question about MIDI note quantization.
If I leave the setting at "hemidemisemiquaver", the import works. However, if I
choose "demisemiquaver", MuseScore segfaults... My goal was to avoid getting alot
of short notes which seems to be a problem with that particular MIDI file...

I any case, MuseScore shouldn't segfault, so I'm submitting this. Attached is
the terminal output of MuseScore as it segfaults.

Best regards
Torquil Sørensen
