Trouble with GnuPG 2.1

[Nils Gillmann]

So I ran into this issue with gpg2.1 on emacs-24.5 and Gnus where
I can *de*crypt emails but I can't encrypt or sign.

Outside of Gnus, gpg works.

So the relevant parts (leaving our filtering, eye candy etc) in
~/.gnus.el are below. If more details I needed or could break the
functionality, I can share the complete configuration.
My ~/.emacs.d/init.el has nothing obvious related to gpg related
modules in it.

;; gnus

(defun gnus-user-format-function-a (header)
  (let ((myself (concat "<" my-mail ">"))
        (references (mail-header-references header))
        (message-id (mail-header-id header)))
    (if (or (and (stringp references)
                 (string-match myself references))
            (and (stringp message-id)
                 (string-match myself message-id)))
