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.
