unity-window-decorator crashed with SIGSEGV in g_cclosure_marshal_VOID__OBJECT()

[Stuart Langridge]

Binary package hint: compiz

Window decorator crashed. I had just started a Java application. There seems to be a similar bug (#724874) but that's marked as fix released, and I am running a totally up-to-date natty as of today (5th April 2011) and it still happened.
