Contacts in "Resources" group do not show listed in the case view

I have created a group called simply "Resources" and configured the CiviCase Settings.xml file to contain the group name such as:
<group name="Resources" />

The group shows up, but the contacts in the group are not listed.

DemeritCowboy was able to reproduce on the demo site here:
http://d7.demo.civicrm.org/civicrm/contact/view/case?reset=1&id=1&cid=90&action=view&context=dashboard&selectedChild=case

And he has theories about the reasons here: http://forum.civicrm.org/index.php/topic,22685.0.html
