-- Information about the crash:
Hi guys,

seems amarokkie doesn't like dragging and dropping - sometimes it crashes when dragging from amarok to dolphin. In this case, dolphin wasn't forthcoming as it was just asking me a question (about overwriting a file). I hit ESC, causing dolphin to cancel the question and amarok to crash...

The crash can be reproduced some of the time.

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