Bug 298760

Application: amarok (2.5.0)
KDE Platform Version: 4.8.2 (4.8.2)
Qt Version: 4.8.1
Operating System: Linux 3.2.0-23-generic x86_64
Distribution: Ubuntu 12.04 LTS

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

Every time I quit Amarok, it crashes, suggests an old bug report that was closed a while ago. Therefore, it must be a new instance or an entirely new problem with the same result. It is reproducable every time I open and quit Amarok.

I am using Kubuntu 12.04, fully updated as of April 24, 2012.

The crash can be reproduced every time.

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