I can confirm this problem. On an aptitude safe-upgrade this morning, firestarter broke with the same error leaving my host unprotected. I had to create manual iptable rules to protect the host.
I attempted a re-install of firestarter and again, firestarter failed to start and all iptable rules where lost. This a critical bug as it leaves host vulnerable. Some details: # grep null /etc/firestarter/configuration IF="(null)" INIF="(null)" ifconfig shows all my network devices working correctly. In my case I did not use X11 on the this host only command line, so I edited the configuration file and fixed the two variables and successfully restarted the firestarter service. On doing a reinstall again, the two variables where null and firestart wound not start an my iptables rule set was empty. Had to re-do fix all over again. This needs to be fixed.
