It looks like parted doesn't like 1 sector partitions that aren't in
order. I can reproduce this by making them at 64s, 66s, then 65s. But if
I make 64s, 65s, 66s it is happy with it, even when printing it later.
I'll look into it more when I have a chance, but I think this is a
corner case that has been there quite a while so it won't make it into
the pending 3.5 release.
