Redhat Linux GNOME startx gave Nautilus setting error

The computer operators just showed me that the usually
working GNOME Redhat GUI just showed a screen/desktop
without the usual icons/shortcut items or menu items in it.

Basically the entire desktop is just a screen of blue background
with "Nautilus setting error " message that pops up if I attempt
to click/do anything.

Attached is the /var/log/Xorg log


I can press Alt-Shift-Fn to get to another text-based virtual console,
login using root but when I tried relaunching the GNOME GUI by entering
"startx" or "gnome-session", it gave a login + password prompt field
& after entering those login credentials, it would give me back the same
plain blue desktop without any shortcuts/menu items

I've also tried deleting away /tmp/.Xauthority, /tmp/.X, /tmp/.gconf
& all files with current date stamp in /tmp & then relaunch startx
as well as rebooting the entire server, remove those gnome
related files but still no joy.

I'll probably use a digital camera tomorrow to snap a photo of this
screen & attach it but appreciate if anyone can have a look in the
meantime & give some suggestions or request for any additional
info
