Vlc crashes when switching interface to qt4

On openSUSE 12.1, when you configure VLC to use the qt interface (this has to be done in the 'show settings: all' view) it simply crashes.

When you start it again, it crashes again during start. Being unable to disable this again, this leaves you with an unworkable VLC.

To disable qt interface, go to your ~/.config/vlc> directory, open vlcrc file and put an '#' before the line 'extraintf=qt4'
