Comment(by erikos):

 As I understand from Bernie's comment the root issue is actually in the X
 server. The commit that should have [http://lists.sugarlabs.org/archive
 /sugar-devel/2010-October/027610.html fixed it] is the following (which is
 part of 1.9.4 the version included in F14):

 commit 9a1bfa5664a80f03cedeb89b9f8a86115a08e7af
 Author: Peter Hutterer <peter.hutterer at who-t.net>
 Date:   Mon Jul 20 16:39:16 2009 +1000

     input: remove XI2 keysym grabs, use keycode grabs instead.

     Keysym grabs are tricky in the details, keycode grabs are known to
 work. So
     for now, provide keycode grabs only.

     Requires inputproto 1.9.99.15.
