skip_authorization_check not working in RSpec testing after an ActiveScaffold controller has been loaded

[Mike Blyth]

This is a strange problem. I am using AS and CanCan and everything seems to be working OK. However, RSpec testing for a certain controller  C fails if an AS controller has been loaded before it. That failing test involves a controller which includes skip_authorization_check to bypass CanCan authorization.

• If I run RSpec for C by itself, it works.
• If I run tests for an AS controller (as_controller_spec) followed by C (c_controller_spec), C fails with CanCan authorization error
  
• If I empty all the tests from the as_controller_spec, and empty all the content from as_controller, C passes
• If I then include only "active_scaffold :group do |config|; end" in as_controller, as below, C fails again.
  

class GroupsController < ApplicationController
  active_scaffold :group do |config|; end
end

• If I add a login to c_controller_spec, it works again.

So it appears that the skip_authorization_check is the piece that is not working. I don't know whether it has something to do with the CanCan bridge or something else.
