Bug 203870

Version:           2.1.1 (using KDE 4.3.0)
OS:                Linux
Installed from:    Ubuntu Packages

Application that crashed: amarok
Version of the application: 2.1.1
KDE Version: 4.3.00 (KDE 4.3.0)
Qt Version: 4.5.2
Operating System: Linux 2.6.30-10-generic i686
Distribution: Ubuntu 9.04

What I was doing when the application crashed:
Steps to reproduce:
1. Start amaroK
2. Activate a dynamic playlist (e.g. play everything at random)
3. Start playing or remove objects from playlist  (even, when not playing music)

This is not always reproducible with the first try. Maybe you have to wait a while letting amarok playing music or do some more changes to the playlist.

 -- Backtrace:
