Trouble with user-switcer applet

["Jóhann B. Guðmundsson" <johannbg hi is>]

When using user-switcher-applet 
I receive Unable to start new display
and the screen locks..

Unlock the screen and
do another switch-user and choose other
screen-locks..
This time I switch user in the unlock screen menu
Get graphical glitch but make it to gdm
see my user account with other choose my self
X crashes and i'm dropped to the gdm screen

Any one else seeing or can confirm this..

Best regards
                 Johann B.
