controller filters running twice in 1.1.4?

since upgrading to 1.1.4 (I had been running without issue on a git snapshot), I'm noticing that my filter actions initiated from application.rb seem to be running twice.  I created a test rails project with the rspec scaffold and am also seeing the same behavior here too.

Adding this code to application.rb:

  before_filter :foo
 
  def foo
    "foo"
  end
 
and an example in users_controller_spec.rb:

    it "should call foo via a before filter" do
      controller.should_receive(:foo)
      do_get
    end

results in this:

1)
Spec::Mocks::MockExpectationError in 'UsersController handling GET /users.xml should call foo'
Mock 'UsersController' expected :foo with (any args) once, but received it twice
script/spec:4:

Is any one else seeing this?

Thanks,
Matt
