As in the bugreport proposed I wrote 

if [[ $XAUTHORITY != ~/.Xauthority ]]; then
    XAUTHORITY=~/.Xauthority xauth merge $XAUTHORITY
    export XAUTHORITY=~/.Xauthority
fi

in my ~/.xsession file but no success.

But there is another (maybe bigger) problem:

giving access to the xserver using 
  xhost +XCLIENT-SERVER # in my case 192.168.0.51

the x2gosession starts - but ends up in several nameless windows with no 
content. This doesn't happen if I open the x2goclient directly in a xserver-
session (without window-manager). Than all works fine.

What does this mean??

cheers
