the ipv6 address does not seem to be a problem for DISPLAY - see

According to Marc Aurele La France
(http://permalink.gmane.org/gmane.network.openssh.devel/13385) this
does not seem to a problem for xorg/xfree86, too.


Maybe I get something wrong, but for now the setting "AdressFamily any"
seems to severely degrade the reliability of X-forwarding setups.
Did someone already file a bug report for this behaviour? I could not
find any. Otherwise I would like to do create one.
