Comment (by nthiery):
Replying to [comment:1 SimonKing]:
> By definition of categories C, for each pair of objects A,B of C, the
morphisms in C from A to B form a set. So, it seems very odd to me that
homsets of schemes currently aren't sets.
Indeed a bug, as we make in
sage.categories.homsets.Homsets.super_categories the assumption that Sage
manipulates only "small categories" whose homsets are therefore sets.
I have tracked down the issue, and am now creating a ticket.
