Problems with dbus_connection_borrow_message

Before getting into specifics, did you see the bit in the documentation
that points out that libdbus is a low-level library and is painful to
use? You would probably be better off with GDBus (part of GLib) or
QtDBus (part of Qt), which interoperate with libdbus and are a lot
easier: in particular, they integrate nicely with the main-loop
conventions of their respective frameworks.

These are low-level functions that you probably shouldn't be using, even
if you are using libdbus. The usual way to receive signals via libdbus
is to add a "filter function", then "dispatch" the connection by either
hooking it up to a main loop or calling

Are you using the right interface name?
Are you using the right signal name?
Did you ask to receive the signals you wanted, by adding a match rule?
