Comment 25 for bug 780961

Some more data, which may or may not be useful:

 I am unable to reproduce this bug using Selene's method (rapidly forcing window redraws) and both my machines having the problem are using the nvidia xorg server.

The only way I've been able to trigger this is to start xterms (and xterms only) (#898214 ) using a sawfish keyboard shortcut that uses run-application.jl (http://sawfish.wikia.com/wiki/Run-application).

I cannot reproduce at will. It doesn't seem to be directly related to the number or xterms I launch or the frequency. I've had the crash happen a minute after X starts and also not until 10 days later.

 iswitch-window (http://sawfish.wikia.com/wiki/Iswitch-window) is the only other lisp code other than key bindings present in both machines that are crashing.
