What ??  Look, if I actually wanted fancy widgets, useless graphical
stuff et al., I would have switched to XEmacs a long time ago <g>.

OK, that was mean, I do apologize.

Nope.  Still have a crash:
$ emacs -geometry 20x5 -q --no-site-file
X protocol error: BadWindow (invalid Window parameter) on protocol request 61

--- end gdb session ---

I diff'ed the two gdb sessions, and apart from line numbers and memory
adresses, there's no differences [I agree that memory addresses can
make a huge difference, but I haven't seen anything suspicious].

Note: This run comes from 21.1 sources plus the 6 patches you already
sent me.  I tried to apply this patch only on 21.1 sources, but then
the patch failed.  So I can not test this patch without the others.
