Here we go:

this time I was actually creating a new frame when the error occurred.
Actually, this error might only occur whenever I create a new frame.  As
I said before, I use a tight integration between my window manager and
emacs, and my window manager creates and deletes emacs frames all the
time.  I am not sure, though.

#+BEGIN_SRC emacs-lisp
(defun a/group-buffer-visisble ()
  (loop
   for frame being the frames
   thereis
   (and (not (a/frame-invisible frame))
        (loop for window being the windows of frame
              thereis (and (eq (window-buffer window)
                               (get-buffer gnus-group-buffer)))))))
#+END_SRC

a/on-window-change is called by window-configuration-change-hook and by
my window manager everytime windows are
selected/deselected/hidden/restored.

Hope this help!
