another problem ...

[Peter Van Epp]

	Since I have two (different) ethernet cards in the machine I swapped
interfaces to make sure this isn't a card issue. While attempting to process
the tcpdump log file with argus_bpf it appeared to hang, and I got a seg
fault on control-Cing:

demoa# ra -r argus.1.log -c -n |grep Wed
demoa# argus_bpf -r tcpdump.1.log -w - |ra -c -n | grep Wed

^CSegmentation fault (core dumped)
