我有一个非常简单的 python 脚本，它通过 XMLRPC (v2) 连接到 MoinMoin wiki 并提取一些数据。这一切都始于一个简单的身份验证：
self._server = xmlrpclib.ServerProxy(self.url)
self.token = self._server.getAuthToken(self.user, self.password)
相同的脚本在某些机器上工作，在其他机器上失败。下面是错误转储，底部是 Apache 日志。
它适用于这台机器：
Python 2.7.3 (default, Feb 27 2014, 19:58:35)
[GCC 4.6.3] on linux2
但它在这台机器上失败了（注意相同的python版本）：
Python 2.7.3 (default, Sep 26 2013, 20:08:41)
[GCC 4.6.3] on linux2
[...]
self.token = self._server.getAuthToken(self.user, self.password)
File "/usr/lib/python2.7/xmlrpclib.py", line 1224, in __call__
return self.__send(self.__name, args)

File "/usr/lib/python2.7/xmlrpclib.py", line 1264, in request
return self.single_request(host, handler, request_body, verbose)
File "/usr/lib/python2.7/xmlrpclib.py", line 1297, in single_request
return self.parse_response(response)

return u.close()
File "/usr/lib/python2.7/xmlrpclib.py", line 791, in close
raise ResponseError()
xmlrpclib.ResponseError: ResponseError()
它在这台机器上也失败了（同样的错误，显然不同的行号）：
Python 2.6.5 (r265:79063, Sep 26 2013, 18:48:04)
[GCC 4.4.3] on linux2

MoinMoin 服务器详细信息：
Python Version

MoinMoin Version
Release 1.9.7 [Revision release]
这是apache日志（稍后捕获，因此可能不相关；我没有尝试过与时间的互相关）：

有什么线索吗？我真的大吃一惊。
