compiz.real crashed with SIGSEGV

[fox]

Binary package hint: compiz

This error apears after todays update on my Dell Latitude D820.
Now WLAN isn't working anymore, the touchpad setting is far too slow. And after each boot i get error messages that the gnome settings manager wasn't able to start.

sudo dpkg-reconfigure -phigh xserver-xorg

solve some of the problems, but as soon as i enable the restricted nvidia driver again, the problems start again too.
