Application: amarok (2.8.0)
KDE Platform Version: 4.14.9
Qt Version: 4.8.6
Operating System: Linux 3.16.7-29-desktop x86_64
Distribution: "openSUSE 13.2 (Harlequin) (x86_64)"

-- Information about the crash:
- What I was doing when the application crashed:restarted the app after having installed updates. If someone knows how to get the latest changes with zypper...

- Unusual behavior I noticed:

- Custom settings of the application:I changed backend to vlc after some time on gstreamer. They couldn't read many files, so I updated all packages (sudo zypper dup) and more specifically the codecs. The update worked, because vlc can read everything.

The crash can be reproduced every time.

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