Hey,

I've noticed that Rails 3.2 seems to break the helper methods in my namespaced controller. Example:

```ruby
class Publisher::BaseController < ApplicationController
protected

def current_publisher
Publisher.first
end
helper_method :current_publisher
end

class Publisher::DashboardsController < Publisher::BaseController
def show
@campaigns = current_publisher.campaigns
end
end

```
The `show` action throws the following exception randomly (sometimes it does, sometimes it doesn't):

```
NameError in Publisher::DashboardsController#show

undefined local variable or method `current_publisher' for #

After modifying the base controller file (say, adding whitespace) the error disappears for a while.
