If you try to run the ezfind index script and for whatever reason you forgot to enable ezfind previously, you will still be able to run that script but you'll probably see that all your objects will produce and indexing error.

This is because is eZ Find is not enabled, mapping between datatypes and ezfind attribute types can't be found as they reside in ini files.

In order to not make the dev panic about, it should be good to add an error in this case and don't try to index anything
