Bug 266135

Application: amarok (2.4.0)
KDE Platform Version: 4.6.00 (4.6.0)
Qt Version: 4.7.0
Operating System: Linux 2.6.35-25-generic x86_64
Distribution: Ubuntu 10.10

-- Information about the crash:
- What I was doing when the application crashed: I tried to clear the playlist. I was adding new tracks to the playlist but only one song would play and the playlist would stop. I tried to clear it and create a new one and then Amarok crashed. This happened around five times.

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