compiz crashed with SIGABRT in raise()

[CaladyonEryn]

Just started the desktop in GNOME CLASSIC mode; if restarted, compiz crashes again.
No problems with GNOME mode. Graphic problems with Unity (the panels flicker and sometimes disappear, the panel's shadows are larger than normal).

This installation is an upgrade from 11.10.
