Strange issue in combination with qname-minimsation

Here is my situation:

Unbound: 1.7.1
Listening on IPv4 + IPv6


- Reload Unbound
- Query for $qname on the IPv4 address (good reply)
- Queray again for $qname on the IPv6 address (servfail)

If I disable qname-minimisation it works, there are no servfails.

It doesn't matter if I start with the IPv4 address of the IPv6 address, 
but once it has succesfully resolved over the one, it won't resolver 
over the other.

Can you reproduce?

Bug or feature?
