Q和durandal 2.1的奇怪问题

当我按照Durandal文档中的说明操作并插入

时

system.defer = function (action) {
  var deferred = Q.defer();
  action.call(deferred, deferred);
  var promise = deferred.promise;
  deferred.promise = function() {
      return promise;
  };
  return deferred;
};

当我点击使用路由器的链接时，它就吓坏了：

我不确定是什么导致了这个问题，但是如果我注释掉[Q]补丁，那就完美了。这是一个durandal 2.1问题吗？

Q是否适用于2.1版
