Application that crashed: amarok
Version of the application: 2.2.0
KDE Version: 4.3.2 (KDE 4.3.2)
Qt Version: 4.5.3
Operating System: Linux 2.6.30-ARCH x86_64

What I was doing when the application crashed:
Here's the steps:
1 - Start Amarok
2 - Browse to the Icecast.org streams.
3 - Click any of the main categories to expand the items in it.
4 - Amarok crashes.
This can be reliably reproduced.

 -- Backtrace:
