This shows the contents of https://commons.wikimedia.org/wiki/File:Australian_Christian_College_-_Crest.png. (note the word "Singleton" missing on Commons as the page was moved) The address bar however says "Singleton". The "Add local description source" link goes to https://en.wikipedia.org/w/index.php?title=File:Australian_Christian_College_-_Crest.png&action=edit (without the "Singleton"), a page which does not exist on enwiki.
https://en.wikipedia.org/wiki/Special:Export/File:Australian_Christian_College_-_Singleton_Crest.png proves the page does exist on enwiki.
It can be edited by manually visiting https://en.wikipedia.org/w/index.php?title=File:Australian_Christian_College_-_Singleton_Crest.png&action=edit which doesn't seem to be linked anywhere.
[[ https://en.wikipedia.org/wiki/File:Australian_Christian_College_-_Singleton_Crest.png | File:Australian Christian College - Singleton Crest.png ]] (with the Singleton) is listed on https://en.wikipedia.org/wiki/Category:Wikipedia_files_requiring_renaming.
Expected: either the local description is shown, or the page redirects with a "Redirected from.." annotation below "From Wikipedia, the free encyclopedia".
What happen instead: crazy things
