Bug 225839

Application that crashed: amarok
Version of the application: 2.2.2
KDE Version: 4.3.4 (KDE 4.3.4)
Qt Version: 4.5.3
Operating System: Linux 2.6.32-trunk-amd64 x86_64
Distribution: Debian GNU/Linux testing (squeeze)

What I was doing when the application crashed:
No tracks selected from the Jamendo database actually play (they show up normally on the left). Once I try to play a track (placed in the playlist as usual) they will not play. Clicking  on the "Play" arrow produces a search for lyrics but nothing else. After that even tracks from my local collection will not play and Amarok crashes on exiting.

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