compiz crashed with SIGSEGV in nux::WindowCompositor::FindKeyFocusArea()

Bug Description

Running Oneiric on a lenovo T61 laptop. Using Cisco AnyConnect client, and Remmina to connect via RDP to a work computer. The screen/mouse/keyboard froze for a few minutes and then I got the window that compiz crashed.

I tried some keyboard-shortcuts quickly. Compiz crashed and restarted.
(..and now I have a rectangular zoom-area around the mouse curser ;)

Setting Triaged/High, assigining to the Desktop team, milestoning.

This happens any time I switch between desktops quickly...

I got this when I was trying to switch my desktop as well. Attaching log.

Same, just trying to switch desktops. This happens occasionally but at least no data is lost.

I was using Alt+Tab to switch among windows and Compiz crashed

This bug was fixed in the package nux - 1.14.0-0ubuntu1

oneiric has seen the end of its life and is no longer receiving any updates. Marking the oneiric task for this ticket as "Won't Fix".
