I'm not booted into Karmic at the moment where I could try it, but does
"gksu -u gdm gconf-editor" work?  gksu should be used for starting an
X application with alternate privileges, while sudo is used otherwise.

gksu vs. sudo examples:

$ gksu gedit /etc/hosts

vs.

$ sudo nano /etc/hosts

Going a bit further off-topic, if you're editing a text file, look into
sudoedit.
