Yeah, I figured out a solution that works for me:

(defadvice org-todo-list (before org-todo-gen-notmuch activate)
  (let ((buf (get-file-buffer "~/org/notmuch_todo.org")))
    (when buf
      (kill-buffer buf)))
  (call-process "notmuch-org"))

(Together with a not very interesting python script that generates
notmuch_todo.org).

Thanks anyway.

Cheers,
Daniel
