You need to reload policy. make -C /etc/selinux/targeted/src/policy reload
I shouldn't need to, I hadn't *changed* the policy. I guess this was an artefact of the -sources package reloading the policy when it shouldn't - I removed -sources and renamed policy.18.rpmnew over policy.18 and it's OK now.
