If you're developing for Wireshark 1.4.x or 1.5.x, try, when calling stats_tree_register_with_group() or 
stats_tree_register(), passing in a flags argument with TL_REQUIRES_PROTO_TREE (as defined in epan/tap.h) set.  That 
*should* cause the protocol tree to be built and a non-null tree argument to be passed to the tap.

(If you're developing for Wireshark 1.2.x, that option isn't available.)
