libnotify never gets the notification closed message from hildon-home
libnotify never receives the closed notification, and thus never executes the "closed" g_object signal, when a notification is closed via the x button on the notification window in tasknav. this is a fairly critical issue as it causes all libnotify clients (incl sphone) to leak memory whenever a notification is closed via this method.
How to reproduce: unfortunately our old version of notify-send dosent support the -w flag that makes it wait for the notification to close before it exits. one can build this slightly modified version of newer notify-send to repoduce this bug:

#include <string.h>
