[Katello] EPEL package metadata errors on kickstart

I've been trying to complete my first build using Katello/Foreman and I
keep hitting an error with the EPEL repo.

To try a workaround, I've edited the provision template to

repo --name="Extra Packages for Enterprise Linux" --mirrorlist=https://mirrors.fedoraproject.org/metalink?repo=epel-6&arch=x86_64

repo --name="Extra Packages for Enterprise Linux" --baseurl=http://dl.fedoraproject.org/pub/epel/6/x86_64/

Foreman is 1.3.0 as installed via Katello 1.4.15-1.el6

The OS I'm trying to build is CentOS 6 x86_64

I've fetched the ks directly using ?spoof param and get the template and
version I'd expect.

Any ideas?
