KmlLayer error handling in Google Maps

Two years ago I noted that the KmLayer in Google Maps didn’t provide an event to inform me if there was a problem when loading the KML. Things have moved on and an event has been added to the API at some point. Usage is as follows.

  var kmlLayer = new google.maps.KmlLayer(url, { map: map });
  google.maps.event.addListener(kmlLayer, 'status_changed', function() {
    if (kmlLayer.getStatus() == 'OK')
      $('#status').html('KML loading problem - ' + kmlLayer.getStatus());
