signing & encrypting fails

Hi!

If i try to sign & encrypt email the message is signed only and contains

<#secure method=pgpmime mode=encrypt> 

instead of being encrypted.

However, just signing or encrypting works.

Here is my setup:

;; GnuPG setup

;; Here we make button for the multipart 
(setq gnus-buttonized-mime-types 
 '("multipart/encrypted" "multipart/signed"))

;; verify/decrypt only if mml knows about the protocl used
    (setq mm-verify-option 'known)
    (setq mm-decrypt-option 'known)

;; use newer epg
(setq mml2015-use 'epg)
(setq mml2015-encrypt-to-self t)

(setq user-id-to-key-id-alist
      '(("gour <at> mail.inet.hr" "C6E7162D")
          ...        
))
