I could not fix this in Rails 3.2.12, maybe I am missing something.
config/routes.rb
get \"home/index\"
root :to => \"home#index\
While it doesn't answer your specific question, I received the failure with the following in my routes.rb
resources :republishes do
post '/attempt_all', :to => 'republishes/#attempt_all' . . .
which I changed to
resources :republishes do
post '/attempt_all', :to => 'republishes#attempt_all' . . .
Removing the slash fixed my issue.
