Swampman, If you have some thin superglue, I'd put a drop on it, if it soaks completely in add another drop and so forth continuing until it will absorb no more. Don't add too fast or any more than you need to or it will just run where you don't want or need it.
I actually let my first drop dry and sand lightly over it. If it's not filled then the sawdust will settle into the crevice, leave it there and add another small drop, repeat the process as necessary. In the end just lightly sand it in to feather out smoothly. You should be good to go.
I've actually done the same thing with wood glue and sawdust mixed together to fill any crevices but like to at least soak the pin drops with a drop of superglue.
