All dissectors down the stack need to be run even if tree is NULL so that conversations, expert info and other non-tree data still gets populated. The various proto_* functions all handle NULL trees and behave correctly, so the easiest way to fix this would be to simply remove the if (tree) check and leave everything else the way it is. Also, (since I'm feeling super picky today) you don't need to #include <epan/prefs.h> :) Cheers, Evan
