    BUG #480095 (BNC) -  Alpha Search In Proxy Dialog Crashes Evolution.
    
    * proxy-login.c (proxy_login_tree_view_changed_cb): Use the unique
    stamp to catch only the valid iterators.
    
    Bug description:
    If you right mouse click on your Groupwise email account, you can select "Proxy
    Login" and a dialog appears with all of your previously used accounts in a
    list.  If you click focus into the list and then type in a keyboard letter it
    crashes.  This should position you at the first match of that letter, or at
    least not crash :)
