Nognus v0.17 registry problem ?

[Julien Cubizolles <j.cubizolles@free.fr>]

Since updating to release v0.17, gnus wouldn't start, complaining with :

,----
| Debugger entered--Lisp error: (error "Error in ~/.gnus  : eieio-defmethod")
|   signal(error ("Error in ~/.gnus: eieio-defmethod"))   
|   error("Error in %s: %s" "~/.gnus" eieio-defmethod)    
|    byte-code("\303\304\b \211A@)#\207" [file var x error "Error in
| %s: %s"] 5)
|   gnus-read-init-file()
|   gnus-1(nil nil nil)
|   gnus(nil)
|   call-interactively(gnus t nil)
|   execute-extended-command(nil)
|   call-interactively(execute-extended-command nil nil)
`----

I could get gnus to launch by commenting out all lines (see at the end
of this post) relative to the registry in .gnus.el but I've no idea what
causes the problem. I'm running Gnus in 24.0.50.1 on Linux.

Here are the lines commented out :

;; (setq gnus-registry-install t)
;; (require 'gnus-registry)
;; (gnus-registry-initialize)

this fancy split rule :
;; (: gnus-registry-split-fancy-with-parent)

and this line :
;; (setq spam-log-to-registry t)
