It is because emacs-w3m (in reality, w3m) failed to fetch a
newsgroup.  The most likely cause is that you have not set the
NNTPSERVER environment variable.  To do that in Emacs is:

(setenv "NNTPSERVER" "news.gmane.org")

In addition, please use the latest emacs-w3m from CVS.  I've made
a workaround right now so that it may regard news contents (which
w3m returns for news:* urls) as text/html.

(I must confess that this is the first time I tried reading news
with emacs-w3m. ;-)
