My concern is that this is software that enables remote access to parts of my website. Possibly part of a plugin from WordPress. Here is the message mailed to me from my domain. I have a very uncomfortable feeling about it.

/etc/cron.weekly/apt-xapian-index:
Traceback (most recent call last):
  File "/usr/sbin/update-apt-xapian-index", line 108, in <module>

PS. Just because I am paranoid does NOT mean someone is trying to get me.
