Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:
C-x m (compose-mail) fails for me if mail-user-agent is
set to
mh-e-user-agent.
Example sequence:
Here are the entire contents of my .emacs file:
(setq mail-user-agent 'mh-e-user-agent)
I type C-x m. I get this error message:
Wrong type argument: char-or-string-p,
nil
The problem seems to be that mh-smail-batch (in
mh-comp.el)
calls mh-send with a subject equal to nil. Then
mh-send passes
this nil subject to mh-send-sub which passes it on to
mh-insert-fields, which finally tries to insert nil.
The insert
function wants a character or a string, not nil, and
issues the
error message above.
Here's a version of mh-smail-batch that seems to fix
the
problem. All I've done is replace subject with (or
subject "")
in the call to mh-send:
(defun mh-smail-batch (&optional to subject
other-headers &rest ignored)
"Set up a mail composition draft with the MH mail
system.
This function is an entry point to mh-e, the Emacs
front end
to the MH mail system. This function does not prompt
the user
for any header fields, and thus is suitable for use by
programs
that want to create a mail buffer.
Users should use `\\[mh-smail]' to compose mail."
(mh-find-path)
(let ((mh-error-if-no-draft t))
(mh-send (or to "") "" (or subject ""))))

Appears to have already been fixed in 21.0.98. Can't
reproduce.

I see the reported bug in FSF emacs 20.7, which, as far as
I have been able to determine, is the most recent version
of FSF emacs which has been released.
Would it be reasonable to request either investigation of
this bug under the most recent FSF emacs, or access to the
source of the version of mh-e provided in "21.0.98"?

This bug also seems to be fixed in the current mh-e sources
and works in Emacs 20.7 as well.
