An editor performed a pagemove on commons:
- From: File:Living on the Edge of the World.jpg
- To: File:A residential cliff area in the Murree Hills.jpg
The EXIF and description-page contents got moved to the new name, a redirect was created at the old name, and the file itself is no longer present at the old name (not even in the admin-visible deleted history). But there is no file at the new name. The thumbnail is blank and attempts to look at the file itself gives a "File not found" error.
