It is Emacs's bug.  Start emacs with -Q and try below code.

(progn
  (require 'gnutls)
  (open-gnutls-stream "test" "test" "imap.gmail.com" 993))

I think gnutls.el needs autoload definition for
network-stream-certificate function.

I use built-in GnuTLS library for all ecnrypted connection from
Wanderlust and can access IMAPS without any problem.
