The problem is only reproduceable when more than one panel group is present in a dashboard (e.g., when Object Store is enabled in the Project dashboard). A crude way to reproduce the problem and verify a fix is to comment out the "permissions" line in openstack_dashboard/dashboards/project/containers/panel.py to enable the second panel group.
