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

[Phillip Susi]

Binary package hint: compiz

This happens most of the time I start the standhal java based mmo game. It seems to be accompanied by several errors:

(unity-window-decorator:15297): GLib-GObject-CRITICAL **: g_object_get_data: assertion `G_IS_OBJECT (object)' failed
