= phenomenon =
Opera 9 as well as Microsoft Internet Explorer 6 and 7 don't seem to support any HTTP redirects for favicon.ico. This results in no favicon at all, unfortunately both browsers are still very common (even if web developers dislike to hear that).

= recommendation =
Please use [proxy] rather [R=301,L] for favicon.ico at fedorapeople.org for better browser support.
