apt-xapian-index version 0.47ubuntu8 - no change

Similar issue here:
I have a system which was upgraded from 14.04 LTS to 16.04 LTS recently.
Since then I get the weekly errors from /etc/cron.weekly/apt-xapian-index as shown below.
I have already purged python and xapian and re-installed them but no change.

Ubuntu 16.10 problem still exist

Problem is related to package apt-xapian-index. When I downloaded same package but from Debian repo and install it, after clearing /var/cache/apt-xapian-index and /var/lib/apt/lists/ I started update-apt-xapian-index again and everything pass ok. It looks like this problem is solved in Debian Jessie.
