[Python-modules-team] Bug#961169: python-django-navtag: FTBFS with Django 3.x

[Chris Lamb]

Source: python-django-navtag
Version: 2.1.3-2
Severity: normal
User: python-modules-team at lists.alioth.debian.org
Usertags: django-3.x

Dear maintainer,

The version of Django experimental is currently 3.0.6-1. I have built
the 153 reverse-dependencies in unstable against this version and 114
of these build & pass their testsuite successfully. Unfortunately,
python-django-navtag fails to build. Please see:

    http://bugs.debian.org/960890

... for more information. Please use this bug report for queries
or questions regarding Django 3.x that are not specific to this
particular package in order to reduce duplicated work across all of
the bugs.
