Righ now, folder listings from plone.app.contenttypes don't work with plone.app.multilingual.Bug folder_listing broken with p.a.multilingual.
Since plone.app.multilingual is part of the plone core, it should also be included within our ci-tests.
So the problem is not pam related, but still think pam should part of our ci-tests.
Where do you get the idea that p.a.multilingual tests are not part of the official Plone test suite? grep for 'plone.app.multilingual' in http://jenkins.plone.org/job/plone-5.1-python-2.7/10/console and you will see that they are indeed part of it.
