Bug 272561

Application: amarok (2.4.0.90)
KDE Platform Version: 4.6.2 (4.6.2)
Qt Version: 4.7.2
Operating System: Linux 2.6.38-9-generic i686
Distribution: Ubuntu 11.04

-- Information about the crash:
- What I was doing when the application crashed:
I used a dynamic playlist and switched manually to the next track. After that, Amarok crashed immediately. Amarok is running under Kubuntu natty, thus gstreamer phonen backend is used.

The crash can be reproduced some of the time.

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