Software Center shows duplicate packages

Status changed to 'Confirmed' because the bug affects multiple users.

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 http://extras.ubuntu.com/ubuntu/ precise main" >> /etc/apt/sources.list
$ sudo apt-get update
$ sudo update-apt-xapian-index
$ SOFTWARE_CENTER_DISTRO_CODENAME=precise ./software-center

This bug was fixed in the package software-center - 5.3.14.3
