Emacs version: "GNU Emacs 23.0.60.1 (x86_64-pc-linux-gnu,
                GTK+ Version 2.12.1) of 2008-01-13 on
                neutrino"
org-mode version: "Org-mode version 5.19a"

I'm not sure it's a problem of a particular emacs version or
of the org-mode, since I updated my emacs and org-mode
together and forget what was the version of org-mode before
updating.
