XEmacs 21.4.14, w3m doesn't start up in x mode

[Norbert Koch <viteno@xxxxxxxxxx>]

This bug report will be sent to the emacs-w3m development team,
 not to your local site managers!!
Please write in simple English, because the emacs-w3m developers
aren't good at English reading. ;-)

Please describe as succinctly as possible:
	- What happened.
	- What you thought should have happened.
	- Precisely what you were doing at the time.

Please also include any Lisp back-traces that you may have.

Dear Bug Team!

First of all, thanks for this wonderful tool!

Using the latest and greatest version of both XEmacs and emacs-w3m I
get the following error on M-x w3m.  It works in TTY mode, though.

Any pointers are welcome,
norbert.
