Crash when a window closes with Alt-tab switcher open

[Alexey Kotlyarov]

When Alt-tab switcher is active, and the window selected in closes, Compiz crashes.

How to reproduce:
1. Open a terminal, run "exec sleep 10".
2. Press Alt-tab, select that terminal window, don't release Alt.
3. Wait for 10 seconds until the terminal closes.

Expected results:
Alt-tab switcher is redrawn with the remaining windows.

Actual results:
Compiz crashes.
