I cleaned up some other issues that showed up. At least one turned up when running "./tshark -G fields >/dev/null"; the others might as well (they were reported as multiple registrations of the same field name when running TShark and Wireshark - one was a duplicate, the other was a case where the script thought two different fields, in the same location in the packet and with the same length, were the same field).
Running "tshark -G fields" (the standard output can probably be discarded - errors *should* go to the standard error) should probably be done after converting a dissector.
