indexing fails after a upgrade if the apt-xapian-index is not yet regenerated

There are two issues here, one is that update-software-center does not index without catalogedtime, that is fixed now.

The other one is that on upgrade we need to run a full re-index of apt-xapian-index so that the cataloged time data is written for all packages. By default the apt-xapian-index weekly cron job rus with "--update" and the dbus service that software-center triggers run with --update as well. But update will only look at the changed packages, in this case (and in every case when a new index plugin is availalbe) we want to do a full-reindex to benefit from the new plugin.

This bug was fixed in the package apt-xapian-index - 0.39ubuntu1

---------------
apt-xapian-index (0.39ubuntu1) maverick; urgency=low

  * debian/postinst:
    - when upgrading, ensure the index is fully rebuild (in the
      background) to ensure that we get updated information in
      /var/lib/apt-xapian-index/{index.values} and that the index
      fully utilizes the new plugins (LP: #646018)
