Application that crashed: amarok
Version of the application: 2.1.1
KDE Version: 4.3.1 (KDE 4.3.1)
Qt Version: 4.5.2
Operating System: Linux 2.6.28-11-generic x86_64
Distribution: Ubuntu 9.04

What I was doing when the application crashed:
First, I cleared the playlist, added one track from a remote collection, and tried playing it - but nothing happened.
Then I added two local tracks, one before and one after the remote track, and started playing them. After the first local song ended, Amarok crashed.

 -- Backtrace:
