v2ex首页怎么不能访问了

打开http://www.v2ex.com/以后是这样的

Traceback (most recent call last):
File "/usr/lib/python2.6/site-packages/tornado/web.py", line 988, in _execute
getattr(self, self.request.method.lower())(*args, **kwargs)
File "/www/v2ex/galaxy/handlers/web/system.py", line 37, in get
if len(self.member.my_home) > 0:
TypeError: object of type 'NoneType' has no len()

打开http://www.v2ex.com/go/python 访问正常
