Yes, I've already requested it be fixed. It took several weeks to fix the revision histories for articles in the main name space so it may take a while for them to fix the File namespace also, but it should get fixed sometime in the near future. Also you may already know this, but if you want to link to an image's file page you can do so by putting a colon before File, for example [[:File:Image.jpg]].
It's a quirk of the software that the order you do the edits can cause that behavior. It's also true of the image page at the bottom where it displayes links to pages where the image is used. This also happens when the image is used via a template sometimes. It's not permanent though, the updates get put into a job cue and they are updated when the server isn't busy doing something else. (The basic gist of the issue is that for it to be completely up to date for any given moment would use too many server resources so they don't). I don't know enough about their particular image cache/server architecture to make a guess about what a "reasonable" time frame for them to start showing up (and stop showing up in the unused page) is but since we don't use it to purge images as some wikis do it doesn't really matter, just more of an inconvenience. I'm getting ready to make an up to date list as well that is A-Z and that will update itself as images are added (using parser functions), I'll give you a link when I'm done. --Tlosk talk contr 22:54, November 19, 2009 (UTC)
