Hit a couple of issues with gedit, just documenting them in case others hit the same problems.
X11 connection rejected because of wrong authentication.
This turned out to be because there was already a copy of gedit running on the system.
GConf Error: Failed to contact configuration server; some possible causes are that you need to
enable TCP/IP networking for ORBit, or you have stale NFS locks due to a system crash. See
http://projects.gnome.org/gconf/ for information. (Details - 1: Failed to get connection
to session: /usr/bin/dbus-launch terminated abnormally without any error message)
This turned out to be dbus-launch not being installed on the system.
