Add user by admin console

[kenneth-l-i]

I found that if I create a new user in the admin console (not by click "register" and filling form),
there will be a lot of "site: fatal signal: Segmentation fault" error.
`SIGSEGV: invalid_state
页面错误 /users/
site: fatal signal: Segmentation fault
site died (signal 500, exit -11)

panic: go back

Do not add users manually. Use manage.py adduser instead.
