Something got wrong during an image upload, and now this image:

http://it.wikipedia.org/wiki/Immagine:Moskwaherb.jpg

Cannot be delete with the usual interface. It says that it cannot delete this file:

/usr/local/apache/htdocs/wikipedia.org/upload/it/archive/e/ec/20040901203504!Moskwaherb.jpg

and stops. I tried to overwrite the image and delete it again (a trick that worked on another image), but this time it didn't work.

Can any developer remove this file and page, and anyone has an idea of what's wrong?
