This patch fixes the crash. But I'm not convinced it's the right one,
perhaps the default net parameter logic could be improved instead:
   /* init network clients */
   if (nb_net_clients == 0) {
       /* if no clients, we use a default config */
       pstrcpy(net_clients[0], sizeof(net_clients[0]),
       pstrcpy(net_clients[1], sizeof(net_clients[0]),
       nb_net_clients = 2;

Also one of the network options could be a black hole kind of device,
such that unlike the "none" type, the device exists, it just can't
send or receive anything.
