Earl... ah, I think that TypeError is something different, likely this bug:
https://bugs.launchpad.net/ubuntu/+source/ubiquity/+bug/1374193
https://bugs.launchpad.net/ubuntu/+source/ubiquity/+bug/1064151
https://bugs.launchpad.net/ubuntu/+source/partman-auto/+bug/912031
For the hardware I did this work-around for, Ubiquity didn't actually crash, it just had a junk default hostname that couldn't be used (because it was too long).
