Ahh, vty is virtual terminal.. Thanks! I did that and it doesn't even 
storage the errors in the ~/.xsession-errors. How can I force that? Well, 
the vty doesn't work very well with Nvidia driver, which I can't come back 
to X. But, when I did the vty and I can use gdb, so I use gdb on 
gnome-session and I get like this:

============================
(gdb) bt
#0  0x28c198ef in poll () from /lib/libc.so.5
#1  0x28a09961 in _thread_kern_sched_state_unlock () from

#3  0xd0d0d0d0 in ?? ()
#4  0x7fffffff in ?? ()

============================

Do anyone have the same problem with the logout on today Gnome 2.5.x?
