Rails - Sep 2012 - “Routing Error No route matches {}” when omniauth failed on registration

(Original question was asked here: 
http://stackoverflow.com/questions/11506734/routing-error-no-route-matches-when-omniauth-failed-on-registration
)

I am using omniauth-identity and configure its "fail on registration".

My files:

config/initializers/omniauth.rb

OmniAuth.config.logger = Rails.logger

Rails.application.config.middleware.use OmniAuth::Builder do
  #...
  provider :identity, on_failed_registration: lambda { |env|
    IdentitiesController.action(:new).call(env)
  }
end

config/routes.rb

Wie::Application.routes.draw do
  root to: ''categories#index''

  ActiveAdmin.routes(self)
  devise_for :admin_users, ActiveAdmin::Devise.config

  match ''auth/:provider/callback'', to:
''sessions#create''
  match ''auth/failure'', to:
''sessions#failure''
  match ''signout'', to: ''sessions#destroy'',
as: ''signout''
  resources :identities#, only: [:new]
  resources :categories, path: '''', only: [:index] do
    resources :entries, path: '''', only: [:index, :show]
  end
end

app/controllers/identities_controller.rb

class IdentitiesController < ApplicationController
  def new
    ariane.add "New Account"

    @identity = env[''omniauth.identity'']
  end
end

*When I have a failure on registration (passing incorrect mail), I get the 
following:*

in browser:

Routing Error

No route matches {} Try running rake routes for more information on 
available routes.

in server log:
