To reveal entities, you'd have to use something like WorldEdit, but it's really irrelevant. The point is, that this is more of an annoying quirk of horses than a bug, per se. I'd suggest running in a circle 3 times on a full moon, whilst holding aloft 3 sheaves of wheat. This ritual may summon a horse back from the horse-void. (batteries not included) :)
