PageSweeper not working since upgrading to 1.1.1

Hi, I upgraded from 1.0 to 1.1.1, now my cache sweepers acts up.
They worked perfectly before he upgrade, now I get strange errors.

I have an empty controller, it looks like this:

class PageElementsController < ApplicationController

cache_sweeper :element_sweeper

def element_container_show
render :inline=>""
end
end

The sweeper looks like this:

class ElementSweeper < ActionController::Caching::Sweeper
observe PageElement
end

When I call the action element_container_show, I get this error:

NoMethodError (You have a nil object when you didn’t expect it!
The error occured while evaluating nil.controller_name):

Can anybody reproduce this?

ok, this seems to be an engine problem. Moving this to the engines list
