After today update all categories I tested on pl.wiktionary, are looped at the end. On last page there is "następne 200" (next 200) link, on next page (which is last in category) there is again "następne 200" (next 200) enabled and "poprzednie 200" (prev 200) disabled, and click on "next" returns to last but one page. Looks like link assigned for prev "label" is placed under "next" label.
Happening on all Wikimedia wikis. Example: "next 200" link on http://en.wikipedia.org/w/index.php?title=Category:Stub_categories&from=Vojvodina+geography+stubs points you to http://en.wikipedia.org/w/index.php?title=Category:Stub_categories&until=Vojvodina+geography+stubs&from=Xinjiang+geography+stubs and "next 200" link on that points you back to the first link.
Yes, using [[w:fr:Catégorie:Naissance en 1947]] and [[wikt:en:Category:English nouns]] I confirmed it is neither specific to Polish translation nor to wiktionary. Looks like larger categories in all projects are affected.
Fixed in r51914.
