Yes, the value is nil.

Tried this one and indeed, it works now. Looking at the
org-todo-line-regexp variable I can see it's no longer reported nil.

So it is a customization issue. Now the question is what :-). I should
mention that I am using both dev versions for Emacs and org-mode
(Emacs from bzr from a few days ago and org-mode from git from a few
days ago) on Mac OS X 10.7. Emacs is installed using homebrew.
