>From what I can tell, iPhoto 6 registers a MIME type handler of
"application/photo" with the latest version of Safari (included in
10.4.4). With this handler, Apple redirects to the feed URL. Without
this handler, Apple redirects to the error page.
No matter. I've written a Greasemonkey script that completely
replaces the error page with something more useful (inspired by
FeedBurner's friendly subscription pages).
