Good catch, I suppose.  I've eliminated this stuff in my Emacs for some
time.  Basically, the function no_switch_window defined in buffer.c has

if (EQ (minibuf_window, window))
     return "Cannot switch buffers in minibuffer window";

which prints the error message.  Surprisingly no_switch_window is called
by `switch-to-buffer' as

   err = no_switch_window (selected_window);
   if (err)
     /* If can't display in current window, let pop-to-buffer
        try some other window. */
     return call3 (intern ("pop-to-buffer"), buffer, Qnil, norecord);

so Emacs should ignore this but God knows what really happens.

Please file a bug report and we will (hopefully) take care of it.
