[evolution/gnome-3-4] Trust attachments from ~/.kde and ~/.kde4.

[Matthew Barnes <mbarnes src gnome org>]

commit 6d3861030b2c4bafc98029140fcc4bd6c78a1a16
Author: Matthew Barnes <mbarnes redhat com>
Date:   Mon Jul 2 10:45:58 2012 -0400

    Trust attachments from ~/.kde and ~/.kde4.
    
    This came about from a mailing list thread entitled:
    
       Sending photos from digKam: "Skipping suspicious attachment"
    
    Apparently KDE still uses dot-folders quite heavily, despite having
    helped draft the XDG Base Directory Specification.
    
    (cherry picked from commit ae1f880dd8b49003a8c0ec51e977bad5bc6d5329)
