Error on uninstalling #1

Unfortunately if I uninstall the product & remove it from buildout, then the next time I run my Plone site I get this: 

    2016-05-26 15:37:24 WARNING OFS.Uninstalled Could not import class 'UserDataSchemaProvider' from module 'fourdigits.seo.overrides.userdata'

The only way to get around this is to keep the product in buildout.

I don't think we ever uninstalled it :)
