Searching for a purchased app results in 3 results for it

TEST CASE:
1. use software-center and install at least one purchase (can be a $0 purchase)
2. click on "File/Reinstall previous purchases" in the menu
3. wait until the list of previous purchases is available
4. click on "All Software" in the menubar
5. search for the *pkgname* of the purchased app (e.g. vendetta-online)
6. verify that there are three items now in the search results

Original description:

If you purchase an app (say, Braid) or click on "reinstall previous purchases", then search for it from the main screen, you'll see 3 results for it:

1) One will have no icon, will have ratings, and no price
2) One will look normal (icon, ratings, price)
3) One will say "(already purchased)" and not have a price

Screenshot attached. Happens for other purchased apps too.
