Firestarter 1.0.3 Policy modification greyed out?

["A.E.Lawrence" <A.E.Lawrence@lboro.ac.uk>]

I have just tried Firestarter but discover that I cannot Add or remove 
rules using the Policy tab or menu: the Add Rule|Remove Rule |Edit Rule 
 options are all greyed out. I guess this might be a permissions 
problem, but I have not been able to track it down. And neither Googling 
nor searching the list archives revealed anything promising.

All the /etc/firestarter,
/usr/share/gconf/schemas/firestarter.schemas,
and friends seem to have sane permissions (writable by root).

This is firestarter-1.0.3-1.1 under sarge, and it appeared to install 
properly without errors. I am probably missing something trivial. Any 
suggestions?

PS. I should probably have said that firestarter is working: I just want 
to add some rules to modify what is output. I realise that I could do 
that by writing them directly into the appropriate files, but I turned 
to firestarter to reduce the work involved in maintaining my own rules 
for iptables :-)
