If this is a bug please specify versions you're using first.

Django version: 1.8.14

Issue:
in /django_suit-0.2.20-py2.7.egg/suit/templates/admin/submit_line.html

{% if django_version < 1.9 %}
  <a href="delete/" class="text-error deletelink">{% trans "Delete" %}</a>
{% else %}
    {% url opts|admin_urlname:'delete' original.pk|admin_urlquote as delete_url %}
    <a href="{% add_preserved_filters delete_url %}" class="text-error deletelink">{% trans "Delete" %}</a>
{% endif %}

"if django_version < 1.9" was always False.
django_version = (1, 8)
