Comment 7 for bug 1031421

Actually, selecting an item in the menu does only that, it doesn't call set_session() at all. It's when something else call set_session() than a check is done about the menu items (to see if it exists, and set it active if needed). And set_session() with an item is actually only ever called by start_authentication() is called.

That means nothing can set a state variable, unless a callback is added to the menuitems, which might be possible, although I'm not sure how to do it.
