WP does not force category slugs to be unique

[MC_incubus]

Category slugs need to be unique, otherwise /category/foo/music/ will return its posts as well as the posts in /category/bar/music/

When creating or editing a category, WP should probably check for slug conflicts, and append an incremented number to the end to ensure uniqueness, or at least tell the user about the problem so they can manually choose an alternate slug.
