Could you please edebug `display-buffer' and find out how the `let' part
below gets executed in your case

     ((let ((frames (or frame
			(and (or use-pop-up-frames
				 display-buffer-reuse-frames
				 (not (last-nonminibuffer-frame)))
			     0)
			(last-nonminibuffer-frame))))
	(setq window-to-use
	      (catch 'found
		;; Search frames for a window displaying BUFFER.  Return
		;; the selected window only if we are allowed to do so.
		(dolist (window (get-buffer-window-list buffer 'nomini frames))
		  (when (or can-use-selected-window
			    (not (eq (selected-window) window)))
		    (throw 'found window))))))

Thanks, martin.
