I know this isn't as helpful as I could be, but it gives a good place to
start looking.  Near lines 7602 in gnus.el,

      (if (and (zerop (buffer-size))		;; these are eval'ing true
	       (not no-display))		
	  (progn
	    ;; This newsgroup is empty.		
	    (gnus-summary-catchup-and-exit nil t) ;Without confirmations.
		;; this is being called
	    (gnus-message 6 "No unread news")
	    (when kill-buffer
	      (gnus-kill-or-deaden-summary kill-buffer))
	    ;; Return nil from this function.
	    nil)

This is occuring on all my nnfolder newsgroups.  I'll do a further check in
a little bit, and it might have to do with the NOV files, but this is a
problem in sgnus 0.57 (on GNU Emacs 19.30.1).
