Application: amarok (2.3.2)
KDE Platform Version: 4.5.4 (KDE 4.5.4)
Qt Version: 4.7.1
Operating System: Linux 2.6.36-vs-ARCH i686
Distribution (Platform): Archlinux Packages

-- Information about the crash:
- What I was doing when the application crashed:
1. Go to podcast collection
2. Add new folder
3. Rename it to something by double click
4. Add new folder
5. Crash

I reproduced exactly this 2 times, on 3rd time I had to repeat steps 2-4 a few times, and on 4th time I just had to add folder and try to rename it. Each time Amarok crashed.

The crash can be reproduced every time.

-- Backtrace:
