Application: amarok (2.5.0)
KDE Platform Version: 4.7.4 (4.7.4)
Qt Version: 4.7.4
Operating System: Linux 3.0.0-15-generic i686
Distribution: Ubuntu 11.10

-- Information about the crash:
- What I was doing when the application crashed:
Amarok was playing in the systray. I switched phonon backend from vlc to gstreamer and Amarok stopped playing. When I was trying to bring Amarok window to resume playing, systray icon was unresponsive and after a while Amarok crashed.

-- Backtrace:
Application: Amarok (amarok), signal: Segmentation fault
