Application: amarok (2.3.0)
KDE Platform Version: 4.4.2 (KDE 4.4.2)
Qt Version: 4.6.2
Operating System: Linux 2.6.32-24-generic x86_64
Distribution: Ubuntu 10.04.1 LTS

-- Information about the crash:
Basic scenario that is 95.43545% predictable:
1)  Start Amarok & play existing playlist.
2)  Minimize to system tray & restore a dozen or so times (rate a few tracks randomly)
3)  Stop while minimized.
4)  Start while minimized.
5)  Start report to submit crash report.  :-)

Also, randomly, after doing steps 1 & 2, I can't quit from the system tray icon.  I can quit if I restore & then quit.  

 -- Backtrace:
Application: Amarok (amarok), signal: Aborted
