--- Comment #6 from Mpaa mpaa.wiki@gmail.com --- I do not think this is a bug: the specified page does not exist or does not begin with the correct namespace.
Input page does not necessarily belongs to File: namespace.
"If pagename is an image description page, offers to copy the image to the target site. If it is a normal page, it will offer to copy any of the images used on that page, or if the -interwiki argument is used, any of the images used on a page reachable via interwiki links."
Now it fails gracefully, however.
