Native Display Session Exiting

[Linos]

Hello, i am using vnc to access many remote desktops but i have a 
problem, all my desktops use Debian Etch, vnc 4.1.1 and xorg 7.1.0, i 
have the same problem with many different drivers, nvidia, i810, sis, 
etc.., in the Xorg log i have this message (posted after) on startup and 
i can connect to 5900 port without problem with vncviewer on other 
machine but when i exits vncviewer on the client, the Xorg server locks 
up and exists in the server side without any notice in the log, it 
simply closes it, the worst it is that i cant reproduce the problem 
ever, but i have it many many times.
