Seems that the 13.04 to 13.10 upgrade script didn't update ubiquity-frontend-gtk. I changed Bug #1244198 which I reported as a python bug to be an ubiquity bug. However, I'm not a developer so I don't really know what I am doing but sudo apt-get install ubiquity-frontend-gtk seemed to solve everything.
