Application: amarok (2.4.3)
KDE Platform Version: 4.6.5 (4.6.5)
Qt Version: 4.7.3
Operating System: Linux 3.0.0-1-amd64 x86_64
Distribution: Debian GNU/Linux testing (wheezy)

-- Information about the crash:
- What I was doing when the application crashed:
I had a few corrupted files which I couldn't even play but I tried to tag them with MusicBrainz and it resulted in crash (probably when Amarok stared to hash first file).

The crash can be reproduced every time.

-- Backtrace:
Application: Amarok (amarok), signal: Floating point exception
