I can't reproduce this from 'emacs -Q'; could some element of your
configuration be giving rise to this?  Can you try reproducing the
problem from 'emacs -Q'?  Here's what I tried:

0. HOME=$(mktemp -d) emacs -Q
1. (setq gnus-select-method '(nntp "news.gwene.org")) C-x C-e
2. M-x gnus RET
3. ^ C-s gwene RET RET (browse gwene groups)
4. C-s gmane.emacs.devel RET (search for emacs-devel group)
5. u q q (subscribe and return to Group buffer)
6. RET 10 RET RET (select first out of 10 latest articles)

Thanks,
