I was using the to-csv and fastercsv gem. When I commented them out of my environment.rb, the error disappeared. I don't know which gem was causing it, but not using either of them has fixed it for now. I will still need CSV export functionality, but now I can at least test if it doesn't break nested forms .. :)
