Your problems most likely are caused by you returning an array instead 
of a String. I'm surprised Marshal doesn't complain.

class Foo
  def marshal_dump
    Marshal.dump([@version, @data])
  end
  def marshal_load(data)
    @version, @data = *Marshal.load(data)
  end
  ...
end

This works here quite well without any random outtakes. At least I 
haven't yet hit one.
