Problem with Gnus and BBDB

[Nicolas Kowalski <Nicolas.Kowalski@imag.fr>]

Hello.

I recently switched from Pine to Gnus & procmail ; most of all
works. Great work Gnus guys :-).

However, I am unable to make BBDB autocreate records when I enter some
mail group. In my case I just want BBDB create records when I enter
groups with the name beginning with "mail.perso" or "mail.verimag".

I wrote in my .gnus :

[SNIP]

(require 'bbdb)
(require 'gnus-bbdb)
(require 'supercite)

(bbdb-initialize 'gnus 'message 'sc 'w3)

(defun my-bbdb-hook ()
  (setq bbdb/news-auto-create-p
	 (or (string-match "mail.perso" gnus-newsgroup-name)
	     (string-match "mail.verimag" gnus-newsgroup-name))))
(add-hook 'gnus-select-group-hook 'my-bbdb-hook)

[SNIP]


Now, when I enter some mail group with a matching name, then I select
some message, I get some error message: 
"Invalid function: 5".

My configuration is : Gnus 5.8.3 with XEmacs 21.1 (patch 10).
I included the gnus-bbdb.el patch in my load-path.


Any idea ?
Thanks.

Niko.
