ICMP replies may include a small bit of the IP datagram they're
complaining about; I was able to decode that simply by recursively
calling "dissect_ip()" (although, in the case of ICMP, it's only a small
bit - but the dissectors below "dissect_ip()" didn't know that, and one
of them blew up, probably because they ran past the end of the frame and
started dissecting garbage; I need to fix that, and to fix various
dissectors not to run off the end of a packet).
