taxonomy/term aliases plus taxonomy/term/all wildcard in views causing duplicate content

Hello,

I was not sure where to put this, in views or pathauto.

Thought I put it here first and let's see if someone has encountered this before.

I have a free tagging taxonomy, and I configured the automated URL alias to tags/[catpath-raw]

This creates nice URLs like tags/myfreetag, tags/newterm etc.

I also have the taxonomy/term view with the default values enabled including the "all" wildcard and feed view also.

What I notice is that the feed at the bottom of the view is shown as taxonomy/[termid]/all/feed

The problem is Google indexed the taxonomy/[termid]/all pages for the tags vocab isntead of the tags/[catpath-raw] pages potentially causing a duplicate content issue because
taxonomy/[termid]/all is the same as tags/[catpath-raw]

Any advice on how to deal with this?

Ideally I would like to do away with any taxonomy/[termid]/all pages, and have feeds like this:
tags/[catpath-raw]/feed
instead of
taxonomy/[termid]/all/feed

plus tags/[catpath-raw] used in the SERPs instead of taxonomy/[termid]/all
