Anonymous problem: "[17] is not a symbol"

The developer throws a problem that I do not understand.

Using the best gem bugs; here where he gets:

block in constantize (gem) activesupport-3.2.12 / lib / active_support / inflector / methods.rb

  225         names = camel_cased_word.split('::')
  226         names.shift if names.empty? || names.first.empty?
  227 
  228         constant = Object
  229         names.each do |name|
  230           constant = constant.const_defined?(name, false) ? 
                  constant.const_get(name) : constant.const_missing(name)
  231         end
  232         constant
  233       end
  234     end

Additional Information:

Request info:
Request parameters {"controller"=>"devise/sessions", "action"=>"new"}
Rack session       {"session_id"=>"a2bcc708204fb5dce015439f6881f67d","_csrf_token"=>"TzIKUgPy8y4F6kFfkDG/xfgCm4vMqkgReLHbK+cjeFI=", "warden.user.user.key"=>[[17], "$2a$10$/WvxkLxIdgHOMxg8nus6cu"]}


Local Variables:
name      [17]
camel_cased_word [17]
names    [[17]]
constant Object

Any ideas? What additional information would be helpful?

Here is a fragment from the end of the track:

I upgraded from 2.0.4 to 2.2.4, and this happened to me when I switched to the stable branch of my project with the old version. The solution was to clear all cookies in the browser for my localhost. In your case, it will be the server on which your application is running.
