Bug 307184

Application: amarok (2.6.0)
KDE Platform Version: 4.9.1
Qt Version: 4.8.2
Operating System: Linux 3.2.0-30-generic x86_64
Distribution: Linux Mint 13 Maya

-- Information about the crash:
- What I was doing when the application crashed:

I opened up Amarok and it usually seg faults approximately 5-8 times, and then loads successfully. I'm guessing it may be my collection of music (9,000 songs, quite a few .flac files), or looking for high resolution cover art.

The crash can be reproduced every time.

-- Backtrace:
Application: Amarok (amarok), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
