--- Comment #2 from Fabian CommodoreFabianus@gmx.de --- Well in the case of vikidia it assumes that the language code 'de' is a part of the family, but the Special:Interwiki page reveals that it's actually another wiki (http://grundschulwiki.zum.de/wiki/Hauptseite , although I don't know if they are affiliated): http://en.vikidia.org/wiki/Special:Interwiki
And the mainpage of the English Vikidia shows an interwiki link to 'de:': http://en.vikidia.org/w/index.php?title=Main_Page&action=edit
I'm not sure what the solution there is, because it seems like a method which analyses it without any prior checking. The most flexible way would be to use 'APISite.interwiki()' which would tell that there is no family for grundschulwiki.zum.de.
