Just in case this adds anything useful: I've seen this bug on both my
desktop and laptop, both while about to launch a dist-upgrade from
update-manager, exactly when the gksu prompt was supposed to display. In
this incarnation, the bug makes compiz crash, attempting to restart it
by switching to a VT and launching "DISPLAY=:0 unity --replace" briefly
displays a full desktop which cannot be interacted with, and eventually
crash again. The second time I got this, I went to a VT and did "killall
gksu", and only then compiz was able to restart successfully.

So I guess this has to do with gksu's screen grab clashing with the
recent stacking-order compiz fixes (never got this crash before
Thursday). I should add that not every invocation of gksu causes this; a
gksu dialogue correctly popped up while going through the apport bug
reporting process.
