Application that crashed: amarok
Version of the application: 2.0.90
KDE Version: 4.2.85 (KDE 4.2.85 (KDE 4.3 Beta1))
Qt Version: 4.5.1
Operating System: Linux 2.6.28-12-generic i686
Distribution: Ubuntu 9.04

What I was doing when the application crashed:
Crash occured when phonon backend was changed to from Xine to GStreamer.  Change was made in order to re-establish sound as no sound in VLC (or other video players) whilst Amarok 2 was open (and playing music), or after Amarok 2 was closed.

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