Rails 3 beta4 Activesupport error

Reported by Micke Lisinge | June 10th, 2010 @ 03:18 PM

I am using ruby 1.9.1 on Windows and after upgrading from Rails 3 beta3 to beta4 i get this error:

undefined method `consumes?' for ActiveSupport::Multibyte::Chars:Class

in app/controllers/account/register_controller.rb:10:in `signup'

and register_controller looks like

# encoding: utf-8
class Account::RegisterController < ApplicationController

  def signup
    @title = 'Registrering'

    @user = User.new(params[:user])
    if @user.save
      session.delete(:registration_password)
      sign_in @user
    else
      render 'index'
    end
  end

  def index
    @user = User.new
  end

end

Receiving the same error on Ruby 1.9.2 RC1 (ruby 1.9.2dev (2010-07-02 revision 28524) [x86_64-linux])

In console

Calling it a second time gives a different message

-1, does not happen in Linux on 1.9.2 RC1 or 1.9.2-head on a freshly created app using Rails master.

ruby -v => ruby 1.9.2dev (2010-07-02 revision 28524) [x86_64-linux]
```
ruby-1.9.2-rc1 > "foo".truncate(10)
 => "foo" 
ruby-1.9.2-rc1 > "foo".truncate(10)
 => "foo"
```
ruby -v => ruby 1.9.2dev (2010-07-02 revision 28522) [x86_64-linux]
```
ruby-1.9.2-head > "foo".truncate(10)
 => "foo" 
ruby-1.9.2-head > "foo".truncate(10)
 => "foo"
```
