Using 'dpkg-maintscript-helper supports rm_conffile' guards introduces
unreliability into upgrades; it means that the conffile is removed or
not depending on whether dpkg happens to be unpacked before
libreoffice-common.  This seems generally undesirable; it would be
better to enforce a single code path.  (This is academic for Debian
because the version of dpkg in squeeze supported
dpkg-maintscript-helper, hence Severity: wishlist; Ubuntu's last LTS
release didn't have a sufficient version of dpkg for that which is why I
care.)

Since you no longer support lenny backports according to the changelog,
it would be simpler to just use a Pre-Depends and drop the conditionals.
That would also guarantee doing the right thing on direct upgrades from
Ubuntu lucid to precise.  Here's a patch against git master:
