Description Stian Ellingsen 2010-07-14 05:50:25 UTC
abrt 1.1.1 detected a crash.

architecture: i686
Attached file: backtrace
cmdline: lmms
component: lmms
crash_function: QMetaObject::removeGuard
executable: /usr/bin/lmms
global_uuid: 633300443f03d246c8e9119642de5986aed7aecb
package: lmms-0.4.6-2.fc12
rating: 4
reason: Process /usr/bin/lmms was killed by signal 11 (SIGSEGV)
release: Fedora release 12 (Constantine)

LMMS seems to crash randomly while playing instruments, especially when using the GUI keyboard.

Configuring LMMS to use ALSA with the default device (which routes to PulseAudio) seems to make the program crash faster than with ALSA hw:0,0 or direct PulseAudio.

How to reproduce
1. On startup, open the instrument settings for the "Default preset" track.
2. Using the mouse, click and hold on a key on the keyboard that just appeared.
3. Drag the mouse fast left and right for a while, so that the instrument continuously plays different notes.
4. After a while, the UI freezes for a short moment and then disappears.
