I ran into what I would guess is a similar problem to what you were experiencing, Oliver. I realized that in my routes file I was using resource instead of resources. I do not know if you have other actions in your Admin::ReportsController class or what your routes file looks like, but this is how I would tackle the problem if Reports has the standard REST actions.

scope :module => 'Admin' do
  resources :reports do
    get :trips, :on => :collection
  end
end

If that does not apply, run rake routes to see if your routes are configured correctly.
