Gnome dies just before login screen F18

[fedora]

How about correcting that (your last log entries):

Apr  5 18:45:40 localhost abrtd: Duplicate: core backtrace
Apr  5 18:45:40 localhost abrtd: DUP_OF_DIR: 
/var/tmp/abrt/ccpp-2013-03-24-13:37:37-1596
Apr  5 18:45:40 localhost abrtd: Deleting problem directory 
ccpp-2013-04-05-18:45:31-1533 (dup of ccpp-2013-03-24-13:37:37-1596)


What does /var/log/Xorg.0.log say?
