When you go to a website for the first time, many browsers 
(traditionally IE) look for site.com/favicon.ico. They simply issue a 
request to get that file. If it's not there, they don't care. So, the 
error message you see is Zope not being able to traverse to 
/favicon.com. It's a regular NotFoundError, a 404 so to speak.

Btw, Mozilla is a little more sensitive and allows one to specify the 
location of the icon; it can also be in an arbitrary format, such as 
PNG. The Rotterdam skin does this:

   <link rel="icon" type="image/png"
         href="http://localhost:8080/@@/favicon.png" />

As you can see, Rotterdam's favicon is a regular resource, as it should 
be. Maybe we should also register it as a view for ISite so that IE will 
find it right away. Or does IE nowadays support the <link> thing as Mozilla?
