When upgrading to rails 3.2.0 and restarting Webrick, I get the error:

/Users/nico/.rvm/gems/ruby-1.9.2-p290/gems/actionpack-3.2.0/lib/action_dispatch/middleware/stack.rb:119:in assert_index': No such middleware to insert before: "Rack::Sendfile" (RuntimeError)

It seems that this problems comes from the initializer compass.rb where I added the lines:

Rails.configuration.middleware.insert_before('Rack::Sendfile', 'Rack::Static',
:urls => ['/stylesheets'],
:root => "#{Rails.root}/tmp")

Can I safely remove this?

Thanks,
