J s gives (wrong-type-argument listp nnml:)

[Christian Nybø]

(gnus-version)  "Pterodactyl Gnus v0.80"
(emacs-version)
"XEmacs 21.2 \"Aphrodite\" [Lucid] (mips-sgi-irix6.5) of Sat Feb 27
1999 on sgichr"

I sometimes get this error when downloading articles with `J s' in a
plugged state.  It happens with both nntp and nnml groups.

Signaling: (wrong-type-argument listp nnml:)
  gnus-group-category ("nnml+private:list.ditherati")
  gnus-agent-fetch-group-1("nnml+private:list.ditherati" (nnml "private"))
  gnus-agent-fetch-session()
  chr-get-news()
  #<compiled-function nil "...(9)" [gnus-plugged
  gnus-group-get-new-news chr-get-news] 1 nil nil>()
  call-interactively(chr-get-maybe)

Adhering to the documentation of that variable, my .gnus does
(setq gnus-secondary-select-methods '((nnml "private")))

What should I change to avoid this?  It occurs to me that the
following function is the offender:

(defun gnus-group-category (group)
  "Return the category GROUP belongs to."
  (unless gnus-category-group-cache
    (setq gnus-category-group-cache (gnus-make-hashtable 1000))
    (let ((cs gnus-category-alist)
	  groups cat)
      (while (setq cat (pop cs))
	(setq groups (cadddr cat))
	(while groups
	  (gnus-sethash (pop groups) cat gnus-category-group-cache)))))
  (or (gnus-gethash group gnus-category-group-cache)
      (assq 'default gnus-category-alist)))

;;;;, perhaps the following var contains something unexpected?

`gnus-category-alist' (buffer: gnus-agent.el, mode: Emacs-Lisp)

Variable:

  value: ((mail true nil nnml:) (default short nil nil))

  variable not documented

Thanks for any hints.

Could you `(load "gnus-agent.el")' to load an uncompiled Gnus?  That
will give me a much more detailed backtrace.
