Export error. Have a look at my backtrace?

Export error. Have a look at my backtrace?

Hey orgsters,

Export started behaving weirdly for me earlier this week. When I
export to HTML or ASCII to a temporary buffer, I get the attached
backtrace. This occurs in emacs 24 (Aquamacs) with org-mode 7.4. The
error does not occur if I export to file.

Also, exporting to a temporary buffer works as expected in emacs 23.2
with org-mode 7.4 in terminal emacs.

Error occurs with every file I have tried in the past few days. Can
anyone else reproduce? I'll come up with a minimal working example if
needed.

Thanks for any pointers.

Jeff

This is an Aquamacs specific issue, I believe.  What happens is
that Emacs tries to guess the major mode of the temporary
buffer.  Aquamacs has the following entry in either
magic-mode-alist, or magic-fallback-mode-alist.

(objc-mode-buffer-check . objc-mode)

So it calls the objc-mode-buffer-check function, and puts the
buffer in objc-mode if the former returns non-nil.  Here's the
definition of said function:

(defun objc-mode-buffer-check ()
   (if (string-match "\\.m$" buffer-file-name)
       (save-restriction
        (narrow-to-region (point-min)
                          (min (point-max)
                               (+ (point-min) magic-mode-regexp-match-limit)))
        (looking-at "\\(.\\|\n\\)*#\\(include\\|define\\|import\\)"))))


The culprit is the first line, this function should first check
that buffer-file-name is a string before trying to match against
it.  So you should probably shout at the Aquamacs developers :P.

Forwarded to Aquamacs. Thanks.
