compiz crashed with signal 5 in Glib::exception_handlers_invoke()

[marcdutonkin]

As soon as i click right, the decoration of windows disappears, then windows themselves disappear. Then Compiz restarts. This situation can be reproduced. After two or more right clicks, finally the system freezes.

The bug seems to be related to the last update of Ubuntu 12.04 beta (13/03/2012).
