Having luckily only running an upgrade on 1 of my FC20 hosts I found that it has broken the firewall completely, so upgrade at your own peril of losing connectivity to your hosts.
A %x error, can't remember the full details as wanted to get back to a working firewall asap, so reinstalled firewall-config-0.3.8-1.fc20 and the firewalld of the same version.
This is to advise you NOT to update to the 0.3.9 version of the software and wait for the next release!
