Yes you are right, it is a bug by me. It is due to code ensuring that
you get an array if you give size=() being wrong for object arrays.
Anyway it means it fails for size=None and object arrays right now, so
thanks for reporting.
However, it will work perfectly fine for any other size or dtype, so I
hope it is not a big deal for you, as it will give you no trouble if
your real application draws multiple items at once.
