Mediawiki parser does not parse langlinks included in source of talk pages. For wikis having wikibaseclient extension enabled on all talk pages a "language" section is added on sidebar. It does not make sence to show this section if there will never be sitelinks. After [[bugzilla:45581]] is resolved the repository will not contain langlinks for talk pages anymore, too.
Today i saw a patch in trunk (not live) removing this section if there are no langlinks. This would solve the visible problem of this bug. But disabling unneeded wikibase client modification checks for talk pages could still improve performance for edit parser and html renderer.
[replacing wikidata keyword by adding CC - see bug 56417]
