The file File:Полное_собрание_законов_Российской_Империи._Собрание_Первое._Том_41.djvu works fine on commons - https://commons.wikimedia.org/wiki/File:%D0%9F%D0%BE%D0%BB%D0%BD%D0%BE%D0%B5_%D1%81%D0%BE%D0%B1%D1%80%D0%B0%D0%BD%D0%B8%D0%B5_%D0%B7%D0%B0%D0%BA%D0%BE%D0%BD%D0%BE%D0%B2_%D0%A0%D0%BE%D1%81%D1%81%D0%B8%D0%B9%D1%81%D0%BA%D0%BE%D0%B9_%D0%98%D0%BC%D0%BF%D0%B5%D1%80%D0%B8%D0%B8._%D0%A1%D0%BE%D0%B1%D1%80%D0%B0%D0%BD%D0%B8%D0%B5_%D0%9F%D0%B5%D1%80%D0%B2%D0%BE%D0%B5._%D0%A2%D0%BE%D0%BC_41.djvu but on any other wiki reports no pages and 0x0 dimensions (which prevents rendering).

Oddly enough, the img_metadata field can be retrieved fine via the api on all wikis

Possibly something changed with the djvu programs, and it should be broken everywhere, but still works on commons due to caching added in https://gerrit.wikimedia.org/r/#/c/209983/ .
