Additional symptom: I'm having the issue (which may or may not be related?) that Unity detects my 2 displays in twinview as a single display stretching across both screens called "Laptop" already before crashing. That does not seem to normally affect maximize behaviour (i.e. it works as expected before crashing).
I can confirm the issue with Unity (compiz).
