Switching sessions: Activating current session does nothing

[Gold Star]

Coming from Windows to Kubuntu, user switching is counter-intuitive when switching between multiple users. The problem is two fold

1) The "switch user" window does not close after selecting a user to switch to
2) The "switch user" window does not do anything if trying to activate the current session

To reproduce issue:

1) Log in
2) In Kubuntu 13.10, Open kickoff launcher, select leave, then switch user
3) Start a new session
4) Log in to another user such as guest
5) As in step 2, select switch user menu item
6) switch back to the first session
7) Bug #1: Upon switching back to the previous session you will see the "switch user" window (should have been closed after switching -- counter intuitive)
8) Bug #2: The user will click their desired user name and click activate but nothing will happen when trying to activate the current session.

The user doesnt know that the session was actually changed in step 6 because of bug #1 and despite the screen blanking, both sessions look the same.

The next user fail is in step 8 where again, the user will try to activate the desired session again but for some reason activating the session you are already on does nothing (not even closing the window which would make sense)
