Hmmm, not really. I've debugged the gnus-group-list variable and it is
changed twice: once to add dummy.group, and another one to add the
subsequent group, in a chain of calls that starts in
gnus-subscribe-group.

The problem is this code:

(defun gnus-subscribe-newsgroup (newsgroup &optional next)
  "Subscribe new NEWSGROUP.
If NEXT is non-nil, it is inserted before NEXT.  Otherwise it is made
the first newsgroup."
  (save-excursion
    (goto-char (point-min))
    ;; We subscribe the group by changing its level to `subscribed'.
    (gnus-group-change-level
     newsgroup gnus-level-default-subscribed
     gnus-level-killed (or next "dummy.group"))

It is called like (gnus-subscribe-newsgroup "The-new-group"
"dummy.group") Note that by default NEXT is nil. This means that the
next group that is inserted will be injected _before_ dummy.group and
the order is destroyed.

Cheers,
