Yes, that's the thing's purpose, to have a tree that contains
information from other frames so It can be used, for example, to
filter all packets of a call knowing just the calling number.

If I call proto_item_add_xxx from the tap listener it just crashes.

I have to call  "thing_tree()" ( the one that calls
proto_item_add_xxx) from somewhere else. AFAIK I would need either a
hook that calls the dissector after every one else (preety much what I
used to do in packet.c )

attached you'll find the least intrusive way I found to do it.
 
I'd like not to touch any files other than mine but I'm not able.
