Application: amarok (2.2.2)
KDE Platform Version: 4.3.95 (KDE 4.3.95 (KDE 4.4 RC2))
Qt Version: 4.6.0
Operating System: Linux 2.6.32-020632-generic x86_64
Distribution: Ubuntu 9.10

-- Information about the crash:
looks similar to qx11alpha bug marked.  

I select amarok, the icon bounces around my mouse pointer, the UI flashes on the screen, and amarok crashes with a segmentation fault.

i love amarok, but its completely unusable to me in this state.

The crash can be reproduced every time.

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