RefineryCMS - undefined method `escape_path' for Rack::Utils:Module

I'm using refinerycms v 1.0.9 in my project.

When I opening pages which contain images I get an error:

NoMethodError in Admin/images#index

Showing /usr/local/rvm/gems/ruby-1.9.3-p448@fairy/gems/refinerycms-images-1.0.9/app/views/admin/images/_grid_view.html.erb where line #4 raised:

undefined method `escape_path' for Rack::Utils:Module

As I understood method escape_path included in Rack versions newer than mine. My refinery version is using Rack 1.2.8 and I can't update Rack version because in this case Refinery fails.

I believe I've missed something important. How can I solve my problem?

Thanks
