Bug 307030

Application: amarok (2.5.0)
KDE Platform Version: 4.8.5 (4.8.5)
Qt Version: 4.8.1
Operating System: Linux 3.2.0-24-generic x86_64
Distribution: Ubuntu 12.04.1 LTS

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

I know nothing about qt8 and so have no idea if this crash is related to the one published there. I am in Amarok  and Kubuntu 12.04. But I have had the crash in previous versions of Kubuntu.

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".
