Unfortunately not yet.  Right now it happen, but i don't know what have
set `minibuffer-completion-table', here his value:

--8<---------------cut here---------------start------------->8---
 (&rest args)
 (apply 'completion-table-with-predicate 'internal-complete-buffer

           3 "\n\n(fn NAME)"]
        'nil args))
--8<---------------cut here---------------end--------------->8---

If i use in tmm-add-prompt:

(all-completions "" minibuffer-completion-table)

instead of

(mapcar 'car minibuffer-completion-table)

i have no error, and a completions buffer with a list of buffers.
