As I understand it, the gksu changes only really help if the launching application is startup notification aware, and sets the environment variables appropriately (usually using libstartup-notification) to pass the timestamp for the launch action through to the new process. So it works great for launches from the panel or applications menu.
The update-notifier applet seems to just do a plain g_spawn() call, which doesn't do the necessary setup.
Yeah, I'm running the latest gksu.
