What will be the final finish?
Different fillers needed for varnished or painted surfaces.
I am not aware of the fillers now available in the UK but I am sure one of Downsizers will point you in the right direction.
If varnishing, it may be best to cut out to a regular shape and then fit a matching piece of wood.

I've seen linseed oil and sand used a gap filler between door frame and opening and it's supposed to be very good as it's slightly flexible. I've not used it myself though to give a qualified comment.
