[William Jon McCann <mccann src gnome org>]

commit a4f59673325ba5aeba0381ffd889bb61bbbaff9f
Author: Ray Strode <rstrode redhat com>
Date:   Mon Mar 15 23:30:01 2010 -0400

    Drop "user-login-frequency-changed" signal in favor of "changed"
    
    It's less specific and will let us handle the other properties changes
    at the same time.
