Disclaimer: This is actually installing the Fedora x86_64 Unity re-spin, so it's possible that this is something that was introduced in that re-spin. In any event, during the installation package selection, there are a couple places where the same package is listed twice in a row: Applications -> Graphics -> dcraw Base System -> System Tools -> audit If there are others, I didn't notice them.
