I have this too.
Happens when gdm's autologon or timedlogon is true.
What happens is when system is booting gdm is auto/timed loging the user
in and the "could not update ICEauthority file" error appears, if OK is
clicked I get another message (usr/lib/libgconf2-4/gconf-sanity-check-2
has quit wi
Some forum told me to chown : the ICEauthority file and
give it 644 permissions.
Did nothing for me.
