Bug#749711: gdm3: When switching between users password requested twice unnecessarily.

[Z]

Package: gdm3
Version: 3.8.4-6
Severity: minor

Dear Maintainer,

I have two users, I'll call them A and B. I was logged onto A, then chose
'switch user' on the menu, and it gave me the login screen, where I logged onto
B. I then went back to A using switch user, and it gave me the login screen
again as desired - so I logged into A. However, after I had typed in my
password, it presented me with the lock screen for A, and I had to type it
again. It makes  sense that it would lock the screen after that amount of time
on another user, but it is completely pointless requiring the user to enter
exactly the same password twice in a row. I had the same going back to B. When
I chose 'log out' from B, it took me straight to A's lock screen, which is fine
as it only requires one password, although unideal if I then wanted to login as
C, and had to click 'log in as another user'.
