Application: amarok (2.3.1)
KDE Platform Version: 4.4.80 (KDE 4.4.80 (KDE 4.5 Beta1))
Qt Version: 4.7.0
Operating System: Linux 2.6.33.5-112.fc13.x86_64 x86_64
Distribution (Platform): Fedora RPMs

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

- Custom settings of the application:
Phonon is using VLC backend.
If I just open and close Amarok, it doesn't crash.
If I open Amarok, play somthing, then close Amarok, it crashes. It doesn't matter whether Amarok finished the last song a long time ago, or if it is currently playing a song, or if a song is paused.

I'm using KDE/Amarok from kde-redhat.sourceforge.net's kde-unstable.

Standalone VLC doesn't crash when playing/closing.

The crash can be reproduced every time.

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