You're feeding gdb the wrong program. It says

So instead of "bin/hobbitd", use "bin/bbtest-net". That should 
(hopefully) give us a much more usable gdb output.

Hmm, pretty generic that one. Anything else in that log?

You can run bbtest-net by hand - with
  $ bbcmd bbtest-net HOSTNAME
where HOSTNAME is the name of one of your hosts. It would be
interesting to know if it crashes if you test only one host - 
that would point to the problem being in global configuration.
If it runs fine with one host, then the problem is probably
in the configuration of one particular host in bb-hosts.

I suspect it is a mis-configuration of one network test, there 
have been some problems with error handling if network tests
(especially URL's in complex web- or ldap-checks) were not
specified correctly.

bin/bbtest-net --version
