Javascript error in IE7 and Opera9

Same syntax problem as http://drupal.org/node/264670 but this time on a different line. This time it's on line 150 of javascript.js:

Before fix:

  var buttons = {
    'popup_ok': {title: Drupal.t('OK'), func: Drupal.popups.close},
  };

After fix:

  var buttons = {
    'popup_ok': {title: Drupal.t('OK'), func: Drupal.popups.close}
  };
