reset-compiz-gconf crashed with GError in __main__: No D-BUS daemon running

[Mathias Lustig]

I can't log in to Unity 3D after latest system updates. All I get is the wallpaper plus mouse cursor an then apport popps up, telling me that compiz crashed. I was able to log in by commandline and I tried to start compiz again from there but with the same result. Compiz keeps crashing after login so I get no usable desktop and unity does not start up.

This behaviour is reproducable and occurs every time I try to log in. The only way out is Xorg restart via magic key.
