Please unblock package apt-xapian-index. It fixes all severe bugs found
after my talk at the MiniDebconf:

apt-xapian-index (0.41) unstable; urgency=low

  * Fixed typo in dbus config
  * Fixed DeprecationWarning in set_sort_by_value. Closes: #601880.
  * Reset cached sort value if --sort is not provided for search.
    Closes: #601881.

A mini feature crept in as part of the fix to #601880, I hope you don't
mind. The deprecation warning required the 2-parameters form of
set_sort_by_value to be used; however, since we were missing reverse
sort (without which sorting by some parameters like package size of age
would be useless), I added the missing parameter with its proper
purpose.

The relevant commit is this:
