Location of bug in WikidataClient suggested to me by Meta administrator Amire80.
On my Wikipedia user pages--which are not listed in Wikidata--the interwiki links section renders correctly in some wikipedias (e.g., en, simple, lad, la, he) but not in others (yi, fr). Where it does not render correctly, there is an extra line with a bullet, but no text and no link. See attached screenshot.
