Call me slow on the uptake. It only took me five weeks to figure out why gwt has been showing the generic www icon instead of my real favicon.
74.125.nnn.nnn - - [01/May/2011:01:03:24 -0700] "GET /favicon.ico HTTP/1.1" 403 476 "-" "-"
74.125.nnn.nnn - - [05/Jun/2011:19:14:19 -0700] "GET /favicon.ico HTTP/1.1" 403 908 "-" "-"
So they've got a special favicon-getting robot that's so far down the hierarchy, they couldn't even be bothered to give it a name.
