Wild guess - maybe you should only handle the Introspect() call if it's 
sent to your object path. It looks like you're sending the reply for the 
/org/bulix/LCD4Linux object regardless of which object was introspected.

If you return NOT_YET_HANDLED if any other object is introspected, then 
libdbus will handle the introspect for you by just listing any 
registered child nodes.

Incidentally,
"/* for reasons unknown, this causes !message->in_cache assertion failures."

The reason is that it causes a double-free of the message, since you 
don't own a ref. You don't need to unref there.
