Application: amarok (2.6.0)
KDE Platform Version: 4.9.2
Qt Version: 4.8.3
Operating System: Linux 3.5.0-18-generic x86_64
Distribution: Ubuntu 12.10

-- Information about the crash:
- What I was doing when the application crashed:
Every time I try to launch Amarok from the sound menu in Ubuntu Unity, I get a crash dialog. Although this crash may have actually happened when I pressed the hardware fast forward (>>|) and play/pause (>/") buttons a couple of times.

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".
