How about the call to x_had_errors_p earlier, on line xfont.c:536?  Is
there any effect if we ignore the error by calling x_clear_errors and
not resetting xfont to NULL?

  xfont = XLoadQueryFont (display, name);
  if (x_had_errors_p (display))
    {
      /* This error is perhaps due to insufficient memory on X server.
	 Let's just ignore it.  */
      x_clear_errors (display);
      xfont = NULL;
    }
