Subject: * Lash up mantis 1064 - nre thrown in
 LandObject.sendLandObjectOwners() * From reading the code, the cause must be
 that a 'show objects on my parcel' is performed when there are objects
 belonging to more than 32 people * I'm not sure why there is a hardcoded 32
 limit but I'm leaving it in place for now.  I don't regard this mantis as
 resolved.
