I can confirm this bug, and maybe help narrow it down:

1. New project
2. Add instrument > Audio File
3. Import Audio File > Select File (test with 3 different files). Add one or more instances to the roll.
4. Press Play and the first iteration of the loop plays
5. If stop is pressed while the first loop is play all is well.
6. If stop is pressed after the first loop has played, CRASH.

I confirm the same bug as above. When importing an mp3, starting playback and stopping playback the program crashes.

Has happened now 3/3 tries with an mp3, and also 1/1 with a wav

Same problem as Sam Hassel, here.

Actually, the crash is a segfault (SIGSEGV), so the offender should be either python or the python's gstreamer binding or gnonlin etc (rather than the - plain python - Jokosher). Here's the console's output :

LOG COMMAND: I0 ToggleSolo(0)
/timeline/playbackbin/Instrument_0/gnlcomposition0.src (gst.GhostPad)
TOTAL TIME TAKEN TO LINK 0.00285410881042
Segmentation fault (core dumped)

I attach the crash report, in case it'd be of use.
