bug#23365: 25.0.93; org-mode fails on export with include

[Phillip Lord]

Emacs fails in org-mode when exporting; testing from current head.

The error is reproducible with emacs -q. Create the following two files.

==== main.org

* Section A

#+include: "a.org"

====

==== a.org

** Section of A

Here is some text

====

Now run C-cC-e h h

Debugger entered--Lisp error: (wrong-type-argument stringp nil)

  funcall-interactively(org-export-dispatch nil)

The error comes from org-map-entries and is not specific to HTML output;
it happens with LaTeX also.

This has been fixed in the org-mode git:
http://orgmode.org/cgit.cgi/org-mode.git/commit/?id=44c8cd7136e3fcd1e6bfa08895cac437b7a691fa

@Stefan: I am copying you on this as the above commit that fixes this in
org-mode git was related to a backport commit from emacs git:
http://orgmode.org/cgit.cgi/org-mode.git/commit/?id=ef9637030456b153fd834f4c9202a9264d5ef18d

So probably the same 44c8cd fix has to be applied to the org.el in
emacs-25/master branches too?

I've checked this a little further -- the current org mode on ELPA does
not fail in the same way -- org-map-entries has changed the call from:

    (org-agenda-prepare-buffers
      (list (buffer-file-name (current-buffer))))

to:

    (org-agenda-prepare-buffers
     (and buffer-file-name (list buffer-file-name)))

which fixes the problem.

Is org-mode in core going to be updated before 25.1?

That's what I said :)

 Copying the org-mode ML for this.

AFAIU, by the time we were ready to merge 8.3, upstream preferred to keep
8.2.

My understanding is that the 8.2-series is not really maintained any
longer, and I don’t know that it contains any promises of forward
comparability.  I guess "backporting" the required changes to Emacs-core
would be the easiest way forward.

Done! Thanks for the feedback.
