libnotify generates a lot of valgrind warnings

[Christophe Dumez]

If you download libnotify examples such as this one:
https://wiki.ubuntu.com/NotificationDevelopmentGuidelines?action=AttachFile&do=view&target=summary-body.c

And compile it using the advised command:
gcc -O0 -ggdb -Wall -Werror `pkg-config --cflags --libs libnotify glib-2.0` summary-body.c -o summary-body

The program runs fine, however it will generate a lot of warnings in valgrind (valgrind --tool=memcheck --leak-check=full ./summary-body 1&>2 2>valgrind.log) when enabling leak-check. I don't know if this is important or not but I thought I should report this.

Note that calling:
g_object_unref(G_OBJECT(notification));
after showing the notification does not help.
