HTML error on groups admin page

The LDAP Groups admin page contains an HTML error:

  $form['system-options'] = array( 
    '#type' => 'fieldset', 
    '#title' => t('Authentication mode'),
    '#description' => t('<p><strong>NOTE: These settings have no effect on Drupal user with uid 1. The admin account never uses LDAP.</p>'), 
    '#collapsible' => TRUE, 
    '#collapsed' => FALSE,
  );

The STRONG tag in the description is not closed. This can be fixed by simply adding the end tag, so I'm not going to add a patch, but will set to RTBC.
