Details

Description:

musescore crashes at startup when pulseaudio driver is selected.

Step to reproduce :
Launch it, 1st time it crashes, sometimes with Segmentation fault (core dumped).
Start it again, a message box displays :

The previous session quit unexpectedly
Restore session ?
YES/NO

If you say YES, mscore starts fine, if you say NO, mscore crashes again.

log files, traces :
Unfortunately, backtrace is pretty useless :

I can't reproduce the crash here, pulseaudio driver works fine. Did you try poking upstream about this?

Now, I can't reproduce theses crashes anymore on my system. This bug has disappeared. I don't know how and when it has been fixed !
