Application: amarok (2.4.0)
KDE Platform Version: 4.5.95 (4.6 RC2)
Qt Version: 4.7.1
Operating System: Linux 2.6.37-desktop i686
Distribution: "openSUSE 11.4 Milestone 5 of 6 (i586)"

-- Information about the crash:
Amarok crashes instantly when VLC backend to Phonon is chosen, and after that crashes every time on startup. Other players (qmmp, SMplayer) works fine with VLC backend. Xine backend doesn't cause any crashes to Amarok.

The crash can be reproduced every time.

-- Backtrace:
Application: Amarok (amarok), signal: Floating point exception
