Description Phillip Kruger 2011-09-20 16:46:31 UTC 
Application: amarok (2.4.3)
KDE Platform Version: 4.7.00 (4.7.0)
Qt Version: 4.7.2
Operating System: Linux 2.6.38-11-generic x86_64
Distribution: Ubuntu 11.04

-- Information about the crash:
- What I was doing when the application crashed:
This happens often when I click next track (either using the button in the GUI or the global shortcut key) - I might click next constantly until I find a song I like, so I click next and as soon as the song start click next again. Please let me know if you need more details - I use GStreamer as the Phonon backend

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