Well, when you open konsole, you logged with an account, the account of user that had start kde.
If you write. "who -w" or "users" you can see the two users, one, who had start kde and two who had start konsole. ok? right?
But if you open four more windows of konsole and the las konsole you can write "who -w" or "users", you can see, that have seven users connected. but if you write exit, in each one of the konsole windows and don't close the last konsole, then you should have two users connected, the user who start kde and the user of the last konsole.
But, NO... if you write "who -w" or "users" you can see, seven users connected.

With previous versions of Konsole or KDE, or other Terminals how "xterm" this situation doesn't happend.

P.D: Please excuse me for my english :P
