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

[William Grant]

Binary package hint: compiz

Upgraded to Unity 3.6.4 an hour or two before, and was doing nothing in particular when the crash occurred. Restarted Unity, all went well for a few minutes, then went to report this bug and radeon started kernel oopsing. So something went fairly bad.
