Application: plasma-desktop (0.4)
KDE Platform Version: 4.6.2 (4.6.2)
Qt Version: 4.7.2
Operating System: Linux 2.6.38-11-generic i686
Distribution: Ubuntu 11.04

-- Information about the crash:
- What I was doing when the application crashed:
Nothing in particular, a few chromium tabs and 2 pdf documents. 
Amarok usually crashes when the first song ends, it freezes and must be killed or it displays an unexpected error with SEGMENTATION FAULT.

I found that the last time it was constatly indexing or searching for music files (i have my music on an external drive). I have recentely install the gstream plugins (the ones marked as bad or ugly restricted)

The crash can be reproduced every time.

-- Backtrace:
Application: Plasma Desktop Shell (plasma-desktop), signal: Segmentation fault
