Status changed to 'Confirmed' because the bug affects multiple users.

That's one of the most reported saucy issues:
https://errors.ubuntu.com/problem/7a3bd8ca84d80c89944f230e3487e4cedc1d9b61

I do not know how to reproduce this exactly.
I logged out then tried to log-in again.
The login screen was behaving as if the password was being checked and it stayed that way for a few minutes.
I logged in into tty2 and sudo shutdown now
When the system restarted and I logged in again this error showed up.

    sequence. (LP: #1185565)
