New crash information added by DrKonqi

amarok (2.5-GIT) on KDE Platform 4.8.90 (4.8.90) using Qt 4.8.2

- What I was doing when the application crashed:

Also Amarok is crashing when a new song in a playlist should start (every time, so far tested only gstreamer backend, the knotify crash happens with both)

-- Backtrace (Reduced):
