Application: plasma-desktop (0.4)
KDE Platform Version: 4.9.4
Qt Version: 4.8.4
Operating System: Linux 3.6.10-2.fc17.i686 i686
Distribution: "Fedora release 17 (Beefy Miracle)"

-- Information about the crash:
- What I was doing when the application crashed:
I closed Amarok using system tray icon -> popup menu -> close option. Then, nothing hapenned for around 2 sec and finally the screen went black (except for a single tiny window with Pidgin tray icon in the top left corner of the screen)

-- Backtrace:
Application: Plasma Desktop Shell (plasma-desktop), signal: Segmentation fault
Using host libthread_db library "/lib/libthread_db.so.1".
