Application that crashed: amarok
Version of the application: 2.2-GIT
KDE Version: 4.3.1 (KDE 4.3.1)
Qt Version: 4.5.2
Operating System: Linux 2.6.30-ARCH i686

What I was doing when the application crashed:
Crashing when scrolling a Magnatune list (using the default gstreamer backend, but also xine, mplayer, and vlc backends). Also, Magnatune works only with the mplayer backend, and with MP3 streaming (no sound when using ogg).

 -- Backtrace:
