Thank you kindly, MCortez, for a patch that:

This hooks up the LandManagementModule to handle the DeedParcelToGroup 
packet. Now people can start testing land assigned to and owned by groups.
Also fixes a viewer crash issue when searching for and then joining a group 
with an agent that is not already being tracked by groups server.
