Was caught PhanTypeExpectedObjectPropAccess critical error by Phan tool in 1224 line of taxonomy_menu/taxonomy_menu.module "Expected an object instance when accessing an instance property, but saw an expression $t with type non-empty-array".
if (i18n_taxonomy_vocabulary_mode($t->vid, I18N_MODE_LOCALIZE)) {

During investigation I found out, that in fact variable $t is a result of _taxonomy_menu_get_item() (in taxonomy_menu.database.inc), which returns stdClass object or false on failure instead array. 

function _taxonomy_menu_get_item($mlid) {
  $result = db_select('taxonomy_menu', 'tm')
    ->condition('mlid', $mlid, '=')
    ->fields('tm', array('tid', 'vid'))
    ->execute();

  return $result->fetch();
}

Variable $result is object of DatabaseStatementBase class("\drupal\includes\database\database.inc"), which set PDO::FETCH_OBJ through constructor

  protected function __construct($dbh) {
    $this->dbh = $dbh;
    $this->setFetchMode(PDO::FETCH_OBJ);
  }

So, I suggest to change returned type of varible for _taxonomy_menu_get_item().
