It's weird that the Compiz update would cause this.  The only changes in
the last Compiz SRU are a blacklist for Nvidia cards for disable X to GL
syncs and the removal of a texturesCache in the animation plugin that
caused issues on Nvidia cards and that's it.  The texturesCache was
unused and only caused issues in the Animation class destructor, so I
fail to see how that could be causing this issue.

And that's it, no other changes, so I'm really thinking Compiz is a
victim here.  Without any other clues such a core dump, it will not be
easy to prove either way who's to blame though.
