Application: amarok (2.4.3)
KDE Platform Version: 4.7.00 (4.7.0) (Compiled from sources)
Qt Version: 4.7.2
Operating System: Linux 2.6.38-10-generic i686
Distribution: Ubuntu 11.04

-- Information about the crash:
- What I was doing when the application crashed:

Audio files located @ Home/Music
User opened file folders and attempted to play file on Amarok media player.
Files appear to be intact, working correctly on alternate player, (Audacity)
Issue is not resolved by restarting application. Removed ~.kde/share/apps/amarok and restarted system. (Kubuntu 11.10.) and attempted to play another media file, with same crash results.

The crash can be reproduced every time.

-- Backtrace:
Application: Amarok (amarok), signal: Segmentation fault
