Binary package hint: compiz

While alt-tabbing with compiz (latest version, 1:0.9.2.1+glibmainloop3-0ubuntu4), i got this crasher.

I've noticed crashers like this for a while since i switched over to natty, but most of the time i was getting traces that were mostly "stack smashers" according to smspillaz.

Withi this one, i think i've put the finger on a more probable cause for the crasher. See stacktrace at http://pastebin.ubuntu.com/544957/ an excerpt of which being:

To reproduce: alt-tab, and sometimes that will crash

mipmap was enabled, though i've had identical crashers when it was disabled as well.
