Shouldn't you be initializing threads earlier than this, before
creating the dbus connection / proxy objects, immediately after
the g_type_init() call. I think you also probably need to call 
dbus_g_thread_init() to initialize dbus' threading support.

/*
 * dbus_g_thread_init:
 *
 * Initializes the D-BUS thread system.
 * This function may only be called
 * once and must be called prior to calling any
 * other function in the D-BUS API.
 */
