Canvas page constantly refreshes

[loganbest]

I'm getting reports that some people are constantly getting page reloads when they visit my app. Looking through forums and everything I'm thinking it may have something to do with the user not being able to get authenticated correctly thus causing this line to be run:

FB.Event.subscribe('auth.login',function(){window.location.reload()});

I was also just now able to reproduce this refreshing on Safari and IE7
