Hi,

Actually, I think it *is* related to my patch - I inserted the code
there in the wrong place or so. I'll find a fix for that when I'm back
home, or you (Cong) can submit yours. It wasn't likely that this was
the problem though, since that's just an error path that should never
happen (we have <30 genl families, and a 16-bit space for their IDs)

Hah, makes sense to me, but I guess we really want Catalin to comment
