"url-handlers.el" is incompatible whih Gnus.

Hello,

 I use CVS Emacs trunk branch and emacs-unicode-2 brach.
 
 When I get messages form web sources in Gnus, such as Web
 search, slashdot or RSS.  I always got this error:

         Debugger entered--Lisp error: (wrong-type-argument stringp nil)
           string-match("\\.\\(arc\\|zip\\|lzh\\|zoo\\|jar\\|sx[dmicw]\\|tar\\)\\'" nil)
           auto-coding-alist-lookup(nil)
           set-auto-coding(nil 54565)
           decode-coding-inserted-region(1 54566 nil nil nil nil nil)
           url-insert-file-contents("http://groups.google.com/groups?q=comp.text.tex&num=100&hq=&hl=&lr=&safe=off&sites=groups")

I have examined the "url-handles.el" in which the
'ur-insert-file-contents' is defined.  I found this problem might be
caused by the codes from line 207 to 211.

	;; FIXME: for text/plain data, we sometimes receive a `charset'
	;; annotation which we could use as a hint of the locale in use
	;; at the remote site.  Not sure how/if that should be done.  --Stef
	(decode-coding-inserted-region
	 start (point) buffer-file-name visit beg end replace)))

The third argument of 'decode-coding-inserted-region', which should
be a file name, is 'nil', for the buffer is not associated whih any
file.


I'm not sure wheather posting this report to this mail list is
appropriate, will you fix this problem?

Cheers
