Application: amarok (2.4.0)
KDE Platform Version: 4.6.2 (4.6.2)
Qt Version: 4.7.2
Operating System: Linux 2.6.38-10-generic i686
Distribution: Ubuntu 11.04

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

I tried to get multiple data from musicbrainz for the metadata of the songs.
Everything works fine but after a few minutes Amarok crashes and Plasma crashes as well.

The crash can be reproduced every time.

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