Still the question below remains. Why is the dissector always called with
a tree != NULL parameter?

I'm really not an expert on this, but as far as I remember:
Any time fields are probably used (filtering, coloring, ...) the tree will be != NULL.
Some things don't need the tree (so it will be tree == NULL) e.g. for the cf_retap_packets() call.
