Please explain this odd lintian error

["Jaldhar H. Vyas" <jaldhar@debian.org>]

lintian -i (v1.20.16) sez:

W: webmin-ssl: postinst-does-not-load-confmodule
N:
N:   Even if your postinst does not involve debconf, you currently need to
N:   make sure it loads one of the debconf libraries. This will be changed
N:   in the future.
N:

But the postinst looks like this:

$ head debian/postinst
#! /bin/sh
# postinst script for webmin
#
# see: dh_installdeb(1)

set -e

# Source debconf library.
. /usr/share/debconf/confmodule
db_version 2.0

Is this a false positive or am I doing something wrong?
