Causes pathauto to create extra aliases in all vocabs

I believe this is an Ubercart issue since Ubercart is exposing their "catalog" vocab to pathauto (right?). If not, feel free to requeue.

I'm running a fresh install of Drupal 6.8 with Ubercart & Pathauto enabled. I set up automatic url aliases for my taxonomies and my catalog. I then add a term to a non-catalog vocabulary, and get the following aliases:

Created new alias foovocab/foo for catalog/60/foo
Created new alias foovocab/foo/feed for catalog/60/foo/feed
Created new alias posts/foo for taxonomy/term/60
Created new alias posts/foo/feed for taxonomy/term/60/feed
Created new term foo.

So I'm getting the correct posts/foo aliases I'm looking for, but Ubercart's also creating extra catalog aliases even though this term and its vocabulary have nothing to do with catalog. Their's not even a shared content type between the catalog and non-catalog vocabs.

Marked minor because the extra aliases don't break anything, but they do create irritating clutter and some double-aliased SEO issues.

Any help is appreciated.
