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

[Eugene Crosser]

Binary package hint: compiz

Apparently (?) this is not the same as #726101 because this happened with compiz 1:0.9.4-0ubuntu7.
Happened a few times, I think mostly when I switch some window between full-screen and non-full-screen modes.

I think that the automatically assigned duplicate status may be wrong because the problem happens with a version that is more recent than the one that purportedly fixed bug #726101.
