Gutsy Tribe4: Change to another user -> bash console

[Reiner Schmid]

Hello,

Today I tried Gutsy Tribe 4  (Edubuntu-Server). Thank you for your 
improvements (particularly ldm2/ltsp).
A bug: I noticed that a logout (thinclient) of the first user causes a 
relapse to a bash console. No graphically ldm for the next user.
So I had to reboot the client for the second user.
