Click https://ru.wikipedia.org/w/index.php?title=File:Callinectes_bocourti_5431018.jpg&action=edit and you can't edit/create the file page.
Click https://en.wikipedia.org/w/index.php?title=File:Callinectes_bocourti_5431018.jpg&action=edit and you can edit/create the file page. Thats how it should be!
A work around is safemode so if you click https://ru.wikipedia.org/w/index.php?title=File:Callinectes_bocourti_5431018.jpg&action=edit&safemode=1 you can edit.
The background for this is in short that a few files exist(ed) on ruwiki without a matching file page. Since all images should have a file page we tried to create it and failed (both me and a local admin). Discussion can be seen at https://ru.wikipedia.org/w/index.php?title=%D0%9E%D0%B1%D1%81%D1%83%D0%B6%D0%B4%D0%B5%D0%BD%D0%B8%D0%B5_%D1%83%D1%87%D0%B0%D1%81%D1%82%D0%BD%D0%B8%D0%BA%D0%B0:Oleg_Yunakov&oldid=145236089#Files_without_a_file_page_and_license
I then asked a steward on meta that also failed to create the page so it is not about missing rights. @HideonRosie succeded in creating the file page using "?safemode=1". See https://meta.wikimedia.org/w/index.php?title=User_talk:EPIC&oldid=28760519#ru:%D0%A4%D0%B0%D0%B9%D0%BB:Asio_logo.gif_etc.
So perhaps a gadget?
