OK, we might have to debug the gconf stuff :).

Before that, try starting a non-GNOME app such as xterm or xeyes.

ls -ld /tmp/dbus-*

Wonder if it's trying to use the wrong socket. There might be a stale
socket since you're running headless, but boot should fix that by cleaning
out /tmp. Does fogtest get shutdown or do you hibernate it?

The obvious solution is you need to start using vim :).
