Upgrading Gnus to 5.2.1, losing some nnml groups

Upgrading Gnus to 5.2.1, losing some nnml groups

[David Allen]

Previous problem fixed (thanks Lars): imported package which I still
have in my .emacs but don't use redefined match-string.

Again, upgrading from sgnus-0.45 to gnus 5.2.1, XEmacs 19.13.

My nnml groups appear to be dead until new mail is received so I can't
go back to read old messages.  The number of messages in the group is
'*' and attempting to select the group gives the trace below.  My mail
setup (ignoring spli methods is:

(defun dja-gnus-summary-exit ()
  (if (string-match "^nndoc" gnus-newsgroup-name)
      (progn
	(beginning-of-buffer)
	(while (not (eobp))
	  (gnus-summary-mark-article-as-read gnus-unread-mark)
	  (gnus-summary-mark-article-as-unread gnus-unread-mark)
	  (forward-line 1)))))
(add-hook 'gnus-summary-prepare-exit-hook 'dja-gnus-summary-exit)
       
(setq nnmail-crash-box "/usr/workspace/gnus/.gnus-crash-box")
(setq nnmail-tmp-directory "/usr/workspace/gnus")
(setq nnml-directory "/usr/workspace/gnus")
(setq nnmail-use-long-file-names nil)
(setq nnmail-crosspost nil)
(setq nnml-get-new-mail t)
(setq gnus-auto-expirable-newsgroups
      (concat "mail.fvwm\\|"
	      "mail.gnus\\|"
	      "mail.sf-written\\|"
	      "mail.sf-tv\\|"
	      "mail.sf-lovers\\|"
	      "mail.cron\\|"
	      "mail.junk\\|"
	      "mail.daemon\\|"
	      "mail.latex2html"))

(setq gnus-secondary-select-methods '((nnml "")))

Also, getting new news seems to be significantly slower.  Are nndoc
groups scanned when getting new news?

Trace from attempting to select an nnml group:

  (let ((group ...) number active marked entry) (or group (error "No group on current line")) (setq marked (nth 3 ...)) (setq number (cond ... ... ...)) (gnus-summary-read-group group (or all ...) no-article)))
  gnus-group-read-group(nil nil nil)
  (if (gnus-group-topic-p) (let (...) (gnus-topic-fold all)) (gnus-group-read-group all no-article group)))
  gnus-topic-read-group(nil)
