I always use self.request.response.redirect(url)

I'm not sure how raise Redirect works.

Are you trying to redirect to the favicon.ico?

I'm not 100% sure but,

Note, if you use redirect you have to take care when you 
are doing this. You can only do this in the view call
but not if the pagelet renders the template, because that's
too late. This is not pagelet specific, that's also the case 
if you render a template in a BrowserPage?
