Thank you for pointing this out.  I've improved this, and also
made external-view[1] work properly.  Could you try CVS?

[1] `w3m-content-type-alist', that specifies external viewers
 corresponding to content types, reads user's ~/.mailcap and
 ~/.mime.types files by using mailcap.elc.  To update the value
 after customizing those files, eval

(makunbound 'w3m-content-type-alist)

 and load w3m.el(c) again.
   If you'd like to customize `w3m-content-type-alist' directly
 instead of customizing the ~/.mailcap file or the ~/.mime.types
 file, not to use the external viewer for image/png for example,
 use this way or the like:

(add-hook
 'w3m-load-hook
 (lambda ()
   (let ((tem (assoc "image/png" w3m-content-type-alist)))
     (if tem
	 (setcdr (cdr tem) '(nil nil))
       (add-to-list
	'w3m-content-type-alist
	'("image/png" "\\.png\\'" nil nil))))))
