This is the applet, right?

Take a look at gnome/applet/applet-dbus-devices.c,
nma_dbus_device_properties_cb().  The code looks like this:

	/* Call the "getProperties" method on each wireless network the device may have. */
	if (num_networks > 0) {
		char ** item;
		for (item = networks; *item; item++)
			nma_dbus_device_update_one_network (applet, op, *item, active_network_path);
	}

you might try printing out what NM returns in the network list (ie,
print the value of "*item" inside the for loop), or using 'nm-tool' to
see what NM reports.  Or

dbus-send --system --dest=org.freedesktop.NetworkManager \
     --print-reply /org/freedesktop/NetworkManager/Devices/ath0 \
     org.freedesktop.NetworkManager.Devices.getProperties

See if any of the network object paths look funny.
