compiz crashes after booting leaving unity unusable

[Jürgen Fuchsberger]

When I try to start a program, compiz chrashes leaving unity unusable.
The clicked program starts, but keyboard does not work anymore, neither the menu is shown. I just can go to tty1 and kill the session.

I had to go into a Gnome session for writing this bug report.

Regards, Jürgen
