Ok, the problem here is a host sending some "client" data without a 
valid hostname or operating-system identifier. A client message should 
begin like

    client jorn,hswn,dk.linux linux

where the first "linux" is the name of the OS of the host. This client 
message that causes the crash doesn't have that. In fact, I don't think 
it has even the hostname.

xymond_client shouldn't crash, of course.

It would be nice to know what kind of client is triggering this. If you
go back into "gdb", then run these three commands:

    fr 6
    p hostname
    p sender

That should give you the hostname this client reports (or NULL, if it 
didn't report one - I suspect that is the case here), and the IP-address 
it was sent from.
