Bug Description

After clicking the "Ubuntu App Showdown winners" banner currently shown on the Software Center, I would expect it to take me to a page where the 3 winners (lightread, fogger, picsaw) are shown.

However, 6 results are displayed (a duplicate for each winner entry) - see the attached screenshot.

A couple of notes:

- The duplicates go away if I click on the "Hide 3 technical items" link
- All 3 apps have been published to by the App Review Board (ARB)
- In comparison with commercial apps in MyApps, there is no PPA publishing for ARB apps. Actually, there is in fact, but it's decoupled from MyApps: the source packages are manually uploaded to the ARB PPA, and then they are copied to extras in an hourly cron job
- The ARB PPA is not enabled on my system

Marked as invalid on the server. Looking into this it seems to be a client-side only issue.

This bug has a similar root cause as #891613 I think.

To reproduce this on quantal you will have to add:
$ echo "deb precise main" >> /etc/apt/sources.list
$ sudo apt-get update
$ sudo update-apt-xapian-index
$ SOFTWARE_CENTER_DISTRO_CODENAME=precise ./software-center
