When you have a redirect page in the File: namespace and try to view a diff of it's history, such as in the url, then only the redirect arrow and target are shown, not the page diff.
Fixed in r67762
I have chosen to force diffonly in this case. The reason is that without diffonly, the content: #REDIRECT [[File:filename.jpg]] will render with the full image included. Alternative suggestions welcome of course.
