--- Comment #31 from Mauren Berti <stormqueen1990@gmail.com> ---
After update to KDE 4.9.1, I tried to use Amarok and it stopped playback after
the second song in playlist. When I hit play, it crashed with a SIGSEGV.
Stacktrace follows:
Application: Amarok (amarok), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
