Application that crashed: amarok
Version of the application: 2.2.0
KDE Version: 4.3.2 (KDE 4.3.2)
Qt Version: 4.5.3
Operating System: Linux 2.6.30-2-amd64 x86_64
Distribution: Debian GNU/Linux testing (squeeze)

What I was doing when the application crashed:
I'm not sure if this is reproducable, but I was trying to randomly seek (which consistently doesn't work when using the currently installed phonon xine backend). The first attempt resulted in stopped playback (very reproducible). The second click on the track position bar caused amarok to crash.

 -- Backtrace:
Application: Amarok (amarok), signal: Aborted
The current source language is "auto; currently c".
