Re: [O] orgmode and auctex

OK so using the setq-default inside a hook is probably not a good idea.  But I can reliably reproduce this problem, I'm surprised you couldn't.  If I start emacs using emacs -Q and open an org file everything is fine.  If I then evaluate this

(setq-default TeX-master nil)

(defun org-mode-reftex-setup ()
  (load-library "reftex")
  (and (buffer-file-name)
       (file-exists-p (buffer-file-name))
  (define-key org-mode-map (kbd "C-c )") 'reftex-citation))
(add-hook 'org-mode-hook 'org-mode-reftex-setup)

and try to open an org file I get prompted "Master file: ~/".  I'm running Ubuntu 11.10 and the emacs-snapshot package: GNU Emacs 23.3.1 (i686-pc-linux-gnu, GTK+ Version 2.24.5), latest org pulled from git today.
Is there any more information I could provide to help diagnose this problem?

Probably not. setq-default sets the default value of the variable
whereas the hook is supposed to set the local value in order to override
the default value: setting the default value from a hook seems backwards
to me.

Actually, I added the above code (*without* the TeX-mode-hook mod) to my
minimal .emacs and opening org files does not generate any questions. Are
you sure you have diagnosed the problem correctly?
