Cannot select Xsession on LightDM after logout.

[NikTh]

I'm not really sure if this is a bug, so I'm sending this here first.
Lubuntu by default comes with 4-5 Xsessions (Lubuntu, Lubuntu Netbook, 
Lubuntu Games..etc). If I logout I cannot select another session. I 
click the icon (up right) but it does not respond.

I can select a session normally in first login though.

To reproduce,
login into Lubuntu session, then logout and try to select another 
session to login.
