Application that crashed: amarok
Version of the application: 2.1-SVN
KDE Version: 4.2.91 (KDE 4.2.91 (KDE 4.3 >= 20090609))
Qt Version: 4.5.1
Operating System: Linux 2.6.29-ARCH i686

What I was doing when the application crashed:
Amarok crashes everytime I begin to scan (re-scan) my library. The progress riches something about 33% and then it breaks.
