Bug#677146: python-uno uses file from libreoffice-core in preinst without declaring PreDepends

[Mike O'Connor <stew@debian.org>]

Package: python-uno
Version: 1:3.5.3-5
Severity: serious
Justification: Policy 7.2

during an upgrade, the python-uno preinst script calls:

/usr/lib/libreoffice/program/unopkg

This file seems to come from the libreoffice-core pacakge.  According
to the policy:

    "Pre-Depends are also required if the preinst script depends on
    the named package"

I found this when helping someone that was having trouble upgrading
from squeeze to wheezy and was getting a preinst failure due to this
file being missing.
