Bug Description

When I switch back to an already open guest session from my user account, I find that the guest session is locked and it asks for the Guest password (which obviously there isn't because it's a guest session!).

Thank you for your bug report, could you log into a guess session and add your .xsession-errors from that session to the bug?

Is this bug going to be fixed? It's very annoying. Here is another .xsession-errors file.

Workaround (if you're root, not suitable for the guest):

Switch to console (Ctrl-Alt-F1), login as user, su -, passwd guest -> choose a valid password, exit console, switch back to X (Ctrl-Alt-F7).

It still affects Trusty 14.04
I ran into this bug while switching to the guest session, back to the user and again back to the guest.
I thought I was stuck on this guest login screen as all functions are inactive on this screen, it only lets you type a password.
But it's possible to switch back to the user login screen using (ctrl-alt-f7) as the guest session is opened in a secondary X server (ctrl-alt-f8).

The user is no more guest as said by Micha B. So to unlock the guest session go to a terminal, use the command "users" to get the name of guest in the shape guest-######. Then "sudo passwd guest-######" to affect a password.
