Description HughDaniel 2011-04-09 08:14:46 UTC 
Application: amarok (2.4.0)
KDE Platform Version: 4.6.2 (4.6.2)
Qt Version: 4.7.2
Operating System: Linux 2.6.38-8-generic x86_64
Distribution: Ubuntu Natty (development branch)

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

For some reaons Amarok stoped making sound, or even progressing though a song (it was in "play" mode but stuck at 0:00).  I changed the music back end from phonon to xine (and that crashed, and I reported it) then it seemed to have switched to xine.  So I clicked ok and back out to Amarok where I hit play and it crashed (as seen in this backtrace).  Amarok was burning two CPU's up for several minutes after it crashed and I was in the crash reporting assistant, but it died on it's own with out a kill from me.

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