script/destroy scaffold

I have created custom scaffold which sets up route like this in manifest: route map.resources :articles, :member => {:da_state => :put, :ne_state => :put}, :path_prefix => ':locale/admin'

Which is fine when doing script/generate, but on destroy I get error:

   route  map.resources :articles, :member => {:da_state => :put, :ne_state => :put}, :path_prefix => ':locale/admin'

/usr/lib/ruby/gems/1.8/gems/rails-2.2.2/lib/rails_generator/commands.rb:531: warning: regexp has invalid interval /usr/lib/ruby/gems/1.8/gems/rails-2.2.2/lib/rails_generator/commands.rb:531: warning: regexp has }' without escape

Problem seams to be fixed after escaping regex in: vendor/rails/railties/lib/rails_generator/commands.rb:531
