Application: amarok (2.2-GIT)
KDE Version: 4.3.70 (KDE 4.3.70 (KDE 4.4 >= 20091002)) (Compiled from sources)
Qt Version: 4.5.2
Operating System: Linux 2.6.30-1-amd64 x86_64
Distribution: Debian GNU/Linux testing (squeeze)

What I was doing when the application crashed:
When I do full rescan of collection amarok crashes. I am experiencing also upredictable crashes during playing song. I think is related to dynamic updates of collection.
