Homepage duplicate Path

Issue Summary

GeoIP and/or Path module are causing the home page for each language to have 2 separate URLs.

http://www.example.com/en
http://www.example.com/en/node ('node' or whatever is set for front on the site information page)

If you type in http://www.example.com you'll be redirected to http://www.example.com/en/node
But if you type in or click a link for http://www.example.com/en it will take you to that path.

I know Google isn't punishing a site to have 2 internal pages identical w/ different paths (duplicate content). I'm not sure how other search engines grade this, but from a users perspective and SEO backlink reasons this should be addressed.
