Well, this function is failing in gnus-registry.el:

(defun gnus-registry-group-count (id)
  "Get the number of groups of a message, based on the message ID."
  (let ((trail (gethash id gnus-registry-hashtb)))
    (if (and trail (listp trail))
    (apply '+ (mapcar (lambda (x) (if (stringp x) 1 0)) trail))
      0)))

and it's failing when it tries to get the id from the
gnus-registry-hashtb, which is nil in the stack trace you sent me.

I think I see the problem.  gnus-registry-read must be called so the
gnus-registry-hashtb variable is initialized (the
gnus-registry-install variable has to be set for that to happen, and
you must read the newsrc).  Somehow one of the two things didn't
happen for you in sequence when you did the stack trace.  I just put
an explicit gnus-registry-read in the gnus-registry.el loading when
gnus-registry-install is set, that should take care of any possible
uninitialized registry variable cases.  See the latest Gnus CVS and
let me know if you have any more problem.

Thanks
