Something is probably wrong with the url in your kickstart.

Still a problem Bug, or not.

Sigh - getting this here too.(In reply to James from comment #7)

Sigh - getting this here as well. Is there a workaround? I had some similar thinks happen when F20 was in beta and downgrading yum made them go away.

Yup - downgrading yum makes it go away here. Before:

I guess I should go search bugs against yum.

It's not a yum bug. It's really a python-imgcreate bug. Though it appears to have been triggered by a change in a library used to get the version of a provides. Also not versioning redhat-release in fedora-release was a contributing factor. For now use the --releasever option.
