Thank you for bearing with me, here are the details.
org-contacts adds completions hooks to message mode:
(when (and org-contacts-enable-completion
(add-hook 'message-mode-hook 'org-contacts-setup-completion-at-point))
(defun org-contacts-setup-completion-at-point ()
"Add `org-contacts-message-complete-function' as a new function
to complete the thing at point."
That function basically checks if this is a place where completion
should happen (To field, for instance), then calls all the
org-contacts-complete-functions until one succeeds. One such function is
org-contacts-complete-group that, in some case, returns a function
taking unused arguments and returning the completion as a string. To
summarize, is it okay for a function in completion-at-point-functions to
return such a function? The docstring seems to say it's OK (except the
function returned should not have any argument), but discouraged. I
guess I should try to return something of the form (start end collection
. props) instead, with collection being a singleton…

Thank you for your help, I'm starting to understand what is going on.
I'll keep digging.
