hobbitd core dumps when receiving a status message on a host not in bb-hosts (snapshot 18 March 2008)

[Sebastian]

Hi,

hobbitd core dumps when receiving a status message on a host not in bb-hosts
(snapshot 18 March 2008).  This may, possibly, just be when the message
comes from a Big Brother server, since that was the case here.  I haven't
tested when the message comes from another Hobbit server and I have now
downgraded again.  However, if needed, I could try reupdating.  Backtraces
follow...

Etc.  More very similar to these.  It would appear that every single one of
these status messages causes a core dump as they happen at approx. 5 minute,
or less, intervals.

Both of these hosts are commented out in bb-hosts, but hobbitd is receiving
updates on them from a Big Brother server (where they should probably be
commented out too, but I found I didn't need to with hobbit 4.2.0, so long
as I don't mind getting the Ghost reports warning).

Kind regards,

Sebastian
