Now I got a crash. Could you please tell me what to examine and how to 
do it?

I am starting to wonder if the problem happens during a call to 
yes-or-no-p in a timer. I have a little library pause.el that does such 
calls to chase me away from the keyboard.



Here are some messages I see before the crash:
