Locking the screen while in a Guest Session makes the session unavailable

Binary package hint: indicator-applet

If you initiate a Guest Session, and then use the indicator-applet-session to lock the screen, you cannot unlock the screen to resume the session because the guest does not have a password. A blank password is not accepted.

I would expect that either 1. Locking the screen would not work in a guest session, or 2. A blank password would unlock the screen, or 3. The guest would be prompted to create a temporary password to unlock the screen upon clicking the lock screen option. Clearly, the third option would be the best, as it's possible a guest user may wish to lock the screen, but it would also be the most difficult to implement.

At this point, locking the screen causes the guest to lose any unsaved work, as there is no way to resume the session once the screen has been locked.
