Bundler.require fails in clean Rails project

Question

My rails app fails to load when I have the following line in application.rb:

Bundler.require(:default, Rails.env)

I get the following error:

Looks as though it's complaining about the params being sent in - which is odd because this is pre-baked Rails stuff. Note that the Bundler.require is application.rb:5 which its complaining about.

I'm on Rails 4, Ruby 2.0.0

Looks like the rollify gem you are using (so it's not clean rails project :P) has some issues in rails 4.x series. Check this out: https://github.com/EppO/rolify/pull/218 there is a fork that already fixes that.
