compiz crashed with SIGSEGV in nux::GetWindowCompositor()

Happens on every time you enable/disable anything in compiz.

This bug is similar to the bug that existed in 11.04 that caused compiz to crash along with the entire desktop manager, so I guess the bug was never fixed? I can't find that bug, so I re-reported it.
