I just downloaded Test3 DVD from torrent (and am letting it seed with 2mbps+ upload :). I'm seeing several problems on my installation. This is the first of them. I'm doing this from memory after a phone call, so I might have forgotten some of the details. In the new network config dialogs, I wanted to set DHCP on one interface and static on the other. I left the defaults on the first interface alone, then unset DHCP on the second interface. I entered an IPv4 address and hit next, with an empty IPv6 address. Anaconda crashed because it couldn't interpret the null IPv6 address. After being forced to reboot, I was more careful about what I set up. So I unset both DHCP and IPv6, and that gave me a different error that was recoverable. Finally, I just cleared everything out and let it do the default, figuring I could change it later, which worked.
