I use 23.2.1 (http://packages.debian.org/squeeze/emacs). Adding (require 'el) works. I tried on another box with the same Emacs (23.2.1 - http://packages.debian.org/wheezy/emacs) and Org, roughly the same configuration, and I can't reproduce the problem, so it's a bit of a mystery for me. Thanks for your answer. -- Sylvain
