Christopher, sorry for the very  late answer.
Yes I'm using GNOME Flashback with Metacity.
I have been using this combination of desktop and WM since Ubuntu 15.04 came out (April).
So it would be hard to say if using Compiz makes any change.
I was watching a movie in VLC then I switched VLC from full screen to windowed mode and clicked around in Firefox I think.
And that is when the crash happened.
I have filed this bug because I thought you can get some hint from the logs regarding some bug that is present.
If the logs are not enough I would say wait if that happens again and see how we can go forward as I would not be happy to use Compiz (I just don't like it) unnecessarily and it also seems that it wouldn't make any sense as the bug is very hard to reproduce.
