Application: amarok (2.5.0)
KDE Platform Version: 4.7.2 (4.7.2) "release 5"
Qt Version: 4.7.4
Operating System: Linux 3.1.9-1.4-default i686
Distribution: "openSUSE 12.1 (i586)"

-- Information about the crash:
- What I was doing when the application crashed:
I added new music collection folder from my usb hdd drive
than i tried to play a song (flac format). Amarok seemed to play the song
(time bar was slided) but I couldn't hear anything
(i have a sound card configuration problem) so i clicked to close the application.
Amarok minimized so I chose quit from the system tray 
and than the crash message appeared. I had dolphin and firefox running at the same time.

The crash can be reproduced every time.

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