Application: amarok (2.5.0)
KDE Platform Version: 4.7.4 (4.7.4)
Qt Version: 4.7.4
Operating System: Linux 3.0.0-16-generic x86_64
Distribution: Ubuntu 11.10

-- Information about the crash:
- What I was doing when the application crashed:
I have an album constisting of musepack-audio-files in my amarok-collection.
I realized, that one song was missing in the collection. I opened the directory containing
these files with nautilus and right clicked on the missing file bringing up the popup-menu
and selected "open with amarok". And then I ended up in the crash-reporting tool :-(

The crash can be reproduced every time.

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