编辑2：通过更改变量PAGESIZE，我可以为最近的实体加载页面。我找不到错误开始/结束的位置：def get(self, cursor=None, limit=60, PAGESIZE = 1):有效，我现在尝试使用更大的PAGESIZE即def get(self, cursor=None, limit=60, PAGESIZE = 10):
答案 0 :(得分：3)
当从数据存储区中提取实体时，复杂的属性类型（以及实体本身）表示为二进制编码的协议缓冲区。此错误意味着无法使用UserProperty协议缓冲区定义对一个特定用户字段中的二进制数据进行反序列化。它可能没有损坏，只是填充了UserProperty以外的东西。
尝试通过数据存储区查看器加载相关实体，以查看实际存储在用户字段中的内容。

这是App Engine数据存储区的已知问题。它与您的代码或应用程序无关。
App Engine团队正在努力修复，在您等待的时候发布了一个解决方法：http://groups.google.com/forum/#!topic/google-appengine-python/ClkOIalYD3s
