Hum... am I missing the point or is that just a matter of redirection
with the favicon (and the Gmail logout CRSF is not really new...) ?

I get approximately the same behavior by just putting a simple
redirection in an apache .htaccess [1].

Moreover just switching between tabs does not log me off on my system
[2] (as it does not reload the nasty icon...).

1. Redirect 301 /favicon.ico http://mail.google.com/mail/?logout
2. Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.8.1.11) Gecko/20071204
Ubuntu/7.10 (gutsy) Firefox/2.0.0.11

Best,
