strange call to a favicon.ico from fusion.google.com

Hello!

I’m having troubles with feedburner service because of a 302 error…

After looking my blog http headers with liveheaders firefox extension, I found a strange call to favicon (from fusion.google.com and its redirected to google.com by the 302 command) that is not in my template and not in any part of the blog as far as I know… but I have checked that it appears even when not redirecting my feeds to feedburner, and I have checked that also appears in other blogs using wordpress that never redirects feeds to feedburner….

So… can someone tell me something about this? I want to eliminate that call! ??
