The sigsegv problem returns after a brief hiatus
ntop ran just fine until I stopped and started it, now it crashes reliably
again :-)
Not sure how to read this gdb output - can someone give me a clue as to
what I'm meant to look for here? Happy to poke around, but its the first
time I've used gdb etc...
