I've done some test and the problem seems be the standard hint "transient"
Example: notify-send -h int:transient:1 "test" "prova" the log is not updated. I've verificated that nm-applet use the "transient" hint: #if HAVE_LIBNOTIFY_07 notify_notification_set_hint (notify, "transient", g_variant_new_boolean (TRUE)); Walter
