I had this in my *mail* buffer (in Mail mode):

======================================================================
Content-Type: text/plain; charset=Utf-8

Test.

<#part type="application/pdf" filename="~/foo.pdf" disposition=attachment>
<#/part>
======================================================================

I ran (mml-secure-message-sign-pgpmime), then typed C-c C-c
and got an error from mml-generate-mime, that assq returned nil here:

	(setcdr (assq 'type (cdr (car cont))) content-type))

cont contained this.

======================================================================
((multipart (sign . "pgpmime") (tag-location . 119) (part (type . "text/plain") (contents . "Test.

")) (part (type . "application/pdf") (filename . "~/foo.pdf") (disposition . "attachment") (tag-location . 152) (contents . ""))))
======================================================================

The code there is kludgy, but in the absence of a precise description
of that data structure, I can't directly tell what's wrong.

Is there a description somewhere?

The rest of the backtrace:
  setcdr(nil "text/plain; charset=Utf-8")
  (progn (setcdr (assq 'type (cdr (car cont))) content-type))
  (if (and (consp (car cont)) (= (length cont) 1) content-type) (progn (setcdr (assq 'type (cdr (car cont))) content-type)))
  (if (not cont) nil (if (and (consp (car cont)) (= (length cont) 1) content-type) (progn (setcdr (assq 'type (cdr (car cont))) content-type))) (if (fboundp 'libxml-parse-html-region) (progn (setq cont (mapcar #'mml-expand-all-html-into-multipart-related cont)))) (prog1 (let ((temp-buffer (generate-new-buffer " *temp*" t))) (save-current-buffer (set-buffer temp-buffer) (unwind-protect (progn (set-buffer-multibyte nil) (setq message-options options) (cond (... ...) (... ...) (t ...)) (setq options message-options) (buffer-string)) (and (buffer-name temp-buffer) (kill-buffer temp-buffer))))) (setq message-options options)))
  (let ((cont (mml-parse)) (mml-multipart-number mml-multipart-number) (options message-options)) (if (not cont) nil (if (and (consp (car cont)) (= (length cont) 1) content-type) (progn (setcdr (assq 'type (cdr (car cont))) content-type))) (if (fboundp 'libxml-parse-html-region) (progn (setq cont (mapcar #'mml-expand-all-html-into-multipart-related cont)))) (prog1 (let ((temp-buffer (generate-new-buffer " *temp*" t))) (save-current-buffer (set-buffer temp-buffer) (unwind-protect (progn (set-buffer-multibyte nil) (setq message-options options) (cond ... ... ...)
