The trigger is when I start an artful lxd container and it tries to get an IPv4/IPv6. Oddly enough, the same thing works perfectly for my xenial container. My lxd-bridge has dnsmasq contained by Apparmor which is non standard but always worked flawlessly.
I can trigger the bug 100% of the time so validating any tentative fix should be easy.
