Database queries for insert, update and delete should use the new database abstraction layer rather than db_query. This is currently causing issues with multisite as values are not inserted into the database correctly in contemplate_refresh_files. It should be:

/**
 * Refresh the listing of template files for the current site
 *
 * This refreshes the file listing whenever a ConTemplate admin screen is called
 */
function contemplate_refresh_files() {
  $data = drupal_system_listing('/\.tpl\.php$/', 'contemplates', 'name', 0);
  $conf = conf_path();
  db_delete('contemplate_files')->condition('site', $conf)->execute();
  if (!empty($data)) {
    $fields = array('site' => $conf, 'data' => serialize($data));
    db_insert('contemplate_files')->fields($fields)->execute();
  }
}

Don't have time to roll a patch right now, but I'll look through for any other instances of this later and make one.
