I'm not quite sure what was going on back in late November / early December, but I tried it with the final http://archive.ubuntu.com/ubuntu/dists/hardy/main/installer-amd64/current/images/netboot/mini.iso and it worked fine, so I think this has gone away now. The syslog Martin posted ("undefined symbol: newt_create_window") is definitely a sign of something still using cdebconf-newt-detect-keys 0.6 for some reason.
