[Orgmode] Emacs hangs forever when running in batch mode and calling a export org function

[Marcelo de Moraes Serpa]

Hello all,

So, I was trying to create a simple bash script to export my org items
as iCal, upload it somewhere and subscribe to it from iCal / Google
Calendar. Here's what I came with:

emacs --batch --eval \
 "(progn \
  (add-to-list 'load-path \"~/.emacs.d/vendor/org/lisp\") \
  (load-file \"~/.emacs.d/vendor/org/lisp/org.el\")
  (load-file \"~/.emacs.d/vendor/org/lisp/org-icalendar.el\") \
 (setq org-combined-agenda-icalendar-file \"~/org/org.ics\") \
 (setq org-agenda-files (quote (\"~/org/gtd/gtd.org\")))
 )" \
 -f org-export-icalendar-combine-agenda-files

If I run the exact same code on a vanilla emacs, it works. If I try to
run this command in the shell, I get the following output:

sh org-ical-export.sh
Loading /Users/fullofcaffeine/.emacs.d/vendor/org/lisp/org.el (source)...
Loading subst-ksc...
Loading subst-gb2312...
Loading subst-big5...
Loading subst-jis...
Loading /Users/fullofcaffeine/.emacs.d/vendor/org/lisp/org-icalendar.el
(source)...

And it hangs forever. No error message nothing.

I've checked the Activity Monitor, and this specific instance of emacs
quickly starts using ~100% of the CPU. However, I can't really debug
what's wrong.

I am on OSX Snow Leopard, GNU Emacs 23.2.1 (x86_64-apple-darwin, NS
apple-appkit-1038.29) of 2010-05-08, org release_7.01h-524-gcf5f.

Any ideas?

Thanks,

Marcelo.
