@1____1: What has robots.txt to do with anything? Its purpose is to prevent crawlers from indexing public resources; browsers simply ignore the whole thing.
@PaoloM: The link works just fine here (IE9). The only issue I observed is when your location settings cause a redirect to a google server in a different domain (e.g. www.google.it). In that case, the fragment is lost and you wind up on an empty home page. Not sure if that's google's fault or IE's.
