Error when restarting gnus

Error when restarting gnus

[Vin Shelton]

I recently added nnfolder to my list of backends.  If I let gnus sit
idle for an hour or so, then quit gnus and restart it, here is the
backtrace I get:

I'm running a gnus built from CVS on July 9, under XEmacs 21.4.
Here's the part of my .gnus.el file that deals with nnfolder:

(setq nnfolder-directory "~/Mail/archive")
(setq gnus-parameters
      '(("nnfolder:xemacs-patches\\..*"
	 ; Setting gnus-visible-headers has no effect.
	 ; Ideally, we would just add Message-id to gnus-visible-headers,
	 ; so I can use 'msgid' to save the message.
	 ; I'll make all headers visible instead (yuck!).
;	 (gnus-visible-headers "^From:\\|^Newsgroups:\\|^Subject:\\|^Date:\\|^Summary:\\|^Keywords:\\|^To:\\|^[BGF]?Cc:\\|^Posted-To:\\|^Resent-From:\\|^X-Sent:\\|^Message-[Ii][Dd]:")
	 (gnus-show-all-headers t)
	 (gnus-large-newsgroup 2000)
	 (display . all))))
(setq gnus-move-split-methods
      '(((equal gnus-newsgroup-name "gnu.emacs.sources") "nnml:emacs")
	((equal gnus-newsgroup-name "rec.humor.funny") "nnml:humor"))
      nnmail-spool-file acs::mailspool
      nnmail-keep-last-article nil	; t if using exmh
;      nnmail-delete-incoming nil	; save a copy of incoming mail
      gnus-secondary-select-methods
      '((nnml "")
	(nnfolder))
      nnmh-get-new-mail nil
      nnmh-be-safe t
      nnml-get-new-mail t
      gnus-treat-display-smileys nil	; don't smilify by default
      gnus-large-newsgroup 1000)

What am I doing wrong?

Thanks in advance,

Sorry to follow-up my own post, but I've gotten no responses.
Since I changed:
(setq
...
      gnus-secondary-select-methods
      '((nnml "")
	(nnfolder))

to:
...

         (nnfolder ""))

I have not seen the error again.  I hope that this really is the
correct fix, and that this report can prove useful to anyone else who
has the same problem in the future.

That does look more correct.  A select method should always have at
least the backend and the server address string.
