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

[Ingo Gerth]

Binary package hint: compiz

This bug occured when I was selecting a ppt presentation using PowerPoint Viewer from the Software Center. Note that I do not think that this is a duplicate of Bug #726101, as it occured to me today on the latest Unity. See attached data.
