Today I was trying to switch some code of mine from old fashion interwiki to wikidata based. I found http://www.mediawiki.org/wiki/Manual:Pywikipediabot/Wikidata#Getting_data page and based on that I wrote:

#!/usr/bin/python

# -*- coding: utf-8  -*-

import wikipedia as pywikibot

if __name__ == "__main__":

    try:

        site = pywikibot.getSite(u'it', u'wikipedia')

        page = pywikibot.Page(site, 'Fabio degli Abati Olivieri')

        data = pywikibot.DataPage(page)

        language_links = data.interwiki()

        for page in language_links:

          print page.title(asLink=True)

    finally:

        pywikibot.stopme()

The output was:

[[commons:fr:Fabio Olivieri]]

[[commons:de:Fabio Olivieri]]

[[commons:it:Fabio degli Abati Olivieri]]

Which seem to point to non existing language specific Commons sites instead of Wikipedias.  I worked around this issue, but what is the source of this issue: Wikidata, Italian Wikipedia, pywikipediabot?
