I agree with Martin, using a minibuffer-only setup doesn't change
things:

1. emacs -Q --eval "(setq initial-frame-alist '((minibuffer . nil)))"
   ;; Now there's a minibufferless frame and a minibuffer-only frame.
2. M-: (setq dired-auto-revert-buffer t)
3. C-x C-f RET ; Now the default directory is shown with point on the
               ; first entry.
4. C-x b ; Back to *scratch*.
5. C-x C-f RET ; Now the default directory is shown with point at
               ; point-min.  This is the bug.

When switch-to-buffer in find-file is replaced by
pop-to-buffer-same-window and the above recipe is repeated, after step 5
point has not moved to point-min but is still on the first entry as in
step 3.  So using pop-to-buffer-same-window works here.  Or does Stefan
have some other setup?
