I had a quick look at the dbus functions. Perhaps you can use dbus_connection_set_wakeup_main_function to set up a function that wakes up your main loop (containing something like: g_main_context_wakeup(g_main_context_default) for gtk+). This will fire the OnIdle event where you can read the message. Another solution can be to launch a thread that executes a loop of dbus reads. You can then communicate back to the main thread.
