nm-applet causing matacity 100% CPU usage via excessive dialog boxes

[willdeans]

metacity uses 100% CPU because "Wireless Network Authentication Required" boxes appear every "few minutes?" and never go away (unless manually closed). Eventually there are hundreds? of them and metacity uses 100% CPU dealing with them.

I don't expect ANY "Wireless Network Authentication Required" box to pop up! I am not trying to authenticate to a wireless network. There doesn't appear to be any non-draconian way to prevent this misbehavior. I do not wish to for instance, "Disconnect".
