Indeed, i have to specify:

--8<---------------cut here---------------start------------->8---
  (with-current-buffer (with-selected-window
                           (minibuffer-selected-window)
                         (current-buffer))
--8<---------------cut here---------------end--------------->8---

instead of

--8<---------------cut here---------------start------------->8---
  (with-current-buffer (current-buffer)
--8<---------------cut here---------------end--------------->8---

Which use the minibuffer only with gnus buffers.
In other place in emacs it use the current-buffer of the selected window
before entering the minibuffer.
