Should I just fill it in?

By the way, here is a picture of the crack.

Does anyone have any opinions? The restoration guy was out today and seemed puzzled by the fact that it doesn't look like there has been much, if any movement. There is a crack in the concrete decking on the other side of the step, and a small hairline crack on the side with the crack, but other than that, it doesn't seem to have moved.
