Application: amarok (2.3.2)
KDE Platform Version: 4.5.1 (KDE 4.5.1)
Qt Version: 4.7.0
Operating System: Linux 2.6.35-24-generic i686
Distribution: Ubuntu 10.10

-- Information about the crash:
- What I was doing when the application crashed:

I was creating dynamic playlists and while fine-tuning the proportions and replacing the list several times amatok crashes 1 out of ten times after getting more and more unresponsive. 
One thing I noticed was a bunch (20-30) kio-http processes.

The crash can be reproduced some of the time.

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