def load_session
  # From trial-and-error, we can change one letter in the name of
  # class in the Marshal-dumped string. So, we can call the backport
  # class FlashGash and use gsub so that Marshal will load the Rails 3.0 session
  # hash using it
  session = Marshal.load @decrypted_session_string.gsub('FlashHash','FlashGash')
  flash_messages_from_original_klass = session.delete('flash')
