This is not a Gnus problem, but Emacs have changed to default to
docview-mode for pdf files, ignoring mailcap.

;;Remove doc-view so pdf will open with ocular
(setcdr
   (assoc "application" mailcap-mime-data)
   (remove '("pdf"
             (viewer . doc-view-mode)
             (type . "application/pdf")
             (test eq window-system 'x))
           (cdr (assoc "application" mailcap-mime-data))))
