that is a good hint - this workaround would help to avoid the use of
the critical poprts around 6000. I applied it here. Thanks!

But still the ipv6 support of openssh seems to be broken, as the
DISPLAY setting always returns the hardcoded ipv4 address "localhost".
This makes it impossible to use a pure ipv6 setup, right?
