Actually, I can reproduce this on two different systems: home (Debian)
and uni (SuSE, the one I am using at the moment).

Here it is 4.3.0.1, at home I don't know.

Shawn already sent me some instructions.  Thanks for this.  Here's the
output of gdb:

I also played around with `deffgcolor' and noticed something strange
(the debugger output for `defwinname' and 'deffgcolor' is practically
the same, AFAICT):

* Start a fresh ratpoison, do `C-t : deffgcolor', hit Return -- crash.

* Start over, do `C-t : deffg[TAB]', hit Return -- no crash, but the bar
shows `<blank space> : black'.

So there's no crash when I use tab completion, but always a crash when I
type the command out on the keyboard.
