Application: amarok (2.3.2)
KDE Platform Version: 4.5.1 (KDE 4.5.1)
Qt Version: 4.7.0
Operating System: Linux 2.6.35-24-generic x86_64
Distribution: Ubuntu 10.10

-- Information about the crash:
- What I was doing when the application crashed:  Playing a dynamic playlist.  Playlist set on standard, but playback stopped after each song.  Tried queing songs from list and playback still stopped.  Finally decided to close amarok.  Right-click in shortcut bar and selected exit.  CPU spiked, waited a few seconds, then Amarok crashs on exit.

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