I have similar problem. It looks like nm-applet lost access to the gnome-keyring and now every time is asking for wireless key, does't remember it, and seemengly spawns the dialog asking for the key indeffinately.. I didn't count the number of windows, but had to click close for quite a while before it went away.
It could conect to the router just fine before, now suddenly (after holidays) started to ask for the key.
