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

[C.H.E.W.S.]

Binary package hint: compiz

I am on a samsung n110 netbook. When using deluge and adding torrent files and switching between google chrome it has crashed multiple times. Also at times it would crash when I was installing stuff in software center tough that was a full compiz crash where the whole interface blanked out and so far seems to have been fixed in update.
