bug#11802: 24.1; Error when viewing message with face header in Gnus

[Frank Schmitt]

I have GNU emacs configured without X running inside GNU screen. When I
open a message containing a face header (e.g. those by Larsi), I get:

Debugger entered--Lisp error: (error "Not an image: nil")
  signal(error ("Not an image: nil"))
  error("Not an image: %s" nil)

  (save-current-buffer (set-buffer gnus-article-buffer) (if interactive 
(call-interactively (quote article-display-face)) (apply (quote 
article-display-face) args)))
  (with-current-buffer gnus-article-buffer (if interactive (call-interactively
