note()ing it seems ok. I'm not sure if it is the best way to test for it 
(something like that seems more like a UI test that would be in 
blackbox/* rather than a direct test.)

I'll also note that if the value is 0, I would still thing a "refusing 
to create an empty bundle" would be a more appropriate result.

Still, it fits the "better than what we have" criteria.
