Well, as I said, nothing too complex I guess, since it's the default file 
from the package. And even with the following file, it segfaults:

hobbit at linuxbox:~$ cat /etc/hobbit/bb-services
          service smtp
             send "mail\r\nquit\r\n"
             expect "220"
             options banner

hobbit at linuxbox:~$  bbtest-net --services --debug 2>&1
Command: bbtest-net '--services' '--debug'
Environment BBLOCATION=''
Environment CONNTEST='TRUE'
Environment IPTEST_2_CLEAR_ON_FAILED_CONN='TRUE'

BBNETSVCS set to : smtp telnet ftp pop pop3 pop-3 ssh imap ssh1 ssh2 imap2

and the strace output of "strace bbtest-net --report --ping

No, it's a fresh install.
