All ref counted object should start with ref count one and be adopted as the
first thing. Therefore if we get an object that does not have one ref here that
is usually a problem. What are the issues caused by this?

I was hitting this at one point but the issue seems to have gone away. Reverted.

I would remove this assert. The assert below will cause a null pointer exception
when !state and that should be enough to catch issues.

Removed.
