RubyInithandler under Apache 2.2.4

Hello,

Apache 2.2.4
Ruby 1.8.6
mod_ruby 1.2.6

I try to use RubyInitHandler:

=========================
.htaccess
==========================
RubyRequire myhandlers.rb

<Files *.html>
    SetHandler ruby-object

    RubyInitHandler MyInitHandler.instance
</Files>


==========================
myhandlers.rb
===========================

require 'singleton'

class MyInitHandler
  include Singleton

  def init( r )
    raise 'in init'
  end
end

===============================

I try to open index.html and have no errors (no error "500"). Why? In
init-method is raise operator.
