 (Sorry, I guess I'm supposed to follow up to gnats-bugs, not admin).
 
 Date: Mon,  4 Jun 2012 13:16:44 -0400 (EDT):
 
 Don't know whether this helps or not, but I was able to get a dump, and a 
ktrace:
 
 What I did, was to:
 
 1.  From fvwm xterm, type "ktrace kmail --nocrashhandler 2>&1 |cat - > 
kmail.log2
 
 2.  Go to the Menu, and select New->Message, then
 
 3.  In the new message window, Go to the Menu, and select "close."
 
 4.  Watch kmail crash, and collect up the dump and the ktrace.
