It looks like a bug in the ubiquity end of migration-assistant. The code in gtkui.py uses '-' as a key for a null username to prevent a partially filled out user details form from appearing wherever a username is not filled in. I know that doesn't make much sense, I'll have to look over that section of code again to give a more thorough explanation.
moma, can you run the installer again with the --debug option (`ubiquity --debug` in a terminal window), and attach /var/log/installer/debug and /var/log/syslog to this bug report? It will make it easier for me to figure out exactly what is going wrong here.
