The hobbitd section reports the following status message:

Latest errormessages:
Invalid client message - blank hostname

Now I would like to see the IP of the server sending this invalid client message to solve the Problem.
OK, added this for the next version.
In general the IP-Adresses of the senders should be checked by comparing it with a nslookup of the hostname, because it's a security issue when any host can send the reports for another host (It works - I just tried!) which could be damaged without that the HobbitMon notices it...
DNS lookups are expensive, and a host may not have a DNS entry at all.
So it's done differently - check the hobbitd(8) man-page for the "--status-senders" option. What you've seen is just the default
behaviour.
