Hi,

I found the root cause to this issue.

it occurring because of secure_compare method in 
lib\ruby\gems\1.9.1\gems\activesupport-2.3.4\lib\active_support\message_verifier.rb

existing method in 2.3.4

      def secure_compare(a, b)
        if a.length == b.length
          result = 0
          for i in 0..(a.length - 1)
            result |= a[i] ^ b[i]
          end
          result == 0
        else
          false
        end
      end

to come out of this issue use below method, if you want.

      def secure_compare(a, b)
        result = a.length ^ b.length
        for i in 0..99 # or some other constant
          result |= a[i].to_i ^ b[i].to_i
        end
        result == 0
      end
