Hi, I have the impression that the package "apt-xapian-index", isn't
present in a **pure** Lubuntu installation and shouldn't be an issue in a
**pure** Lubuntu install. By "pure", I mean an install that doesn't have
any other DE or even a software package installed that could pull in
"apt-xapian-index" as a dependency.

DEs that would pull in apt-xapian-index can be found by running "apt-cache
show apt-xapian-index":
Task: ubuntu-desktop, ubuntu-usb, cloud-image, kubuntu-desktop,
kubuntu-full, kubuntu-active-desktop, kubuntu-active-full, kubuntu-active,
edubuntu-desktop, edubuntu-desktop-kde, edubuntu-usb, xubuntu-desktop,
mythbuntu-frontend, mythbuntu-desktop, mythbuntu-backend-slave,
mythbuntu-backend-master, ubuntustudio-desktop

Lubuntu isn't listed.

An example of installing a software package that would pull in
apt-xapian-index is the Ubuntu Software Center:
apt-get install -s software-center | grep xapian-index
gives me
  apt-xapian-index gir1.2-gmenu-3.0 gir1.2-gudev-1.0
  apt-xapian-index gir1.2-gmenu-3.0 gir1.2-gudev-1.0
Inst apt-xapian-index (0.44ubuntu7 Ubuntu:12.10/quantal [all])
Conf apt-xapian-index (0.44ubuntu7 Ubuntu:12.10/quantal [all])

My install is a pure "Lubuntu" and I don't see "apt-xapian-index" listed
when I check the output of "dpkg --get-selections". And I haven't been
bothered by 100% CPU usage though it was an issue for me when I was on
Ubuntu (http://askubuntu.com/q/79481/25656).

Is it possible OP is seeing the activity because of another DE (even though
OP hasn't logged into it) or a software package?
