nice .. I got response ;)

At least for a (t)csh I can give you a workaround:
copy following snipset to your ".tcshrc" or ".cshrc" and your session 
management will work again. I'm quite sure similar is possible with other 
shells.

---------------
if ( $?command ) then 
  set is_x2go=`echo $command | grep "x2golistsessions"`
  if ( "x$is_x2go" != "x" ) then
      exec x2golistsessions
  endif
endif
--------------

background: when the x2go client starts to communicate with the server 
(one of) the first command is "export HOSTNAME&&x2golistsessions" which is 
necessary for the session-management.

By sure, this is not a solution in general but for simple setups 
it  will be helpful ..
As a long-term objectiv one should put this into the X2Go todo-list where 
the proper handling of different shells is done within the client - armin
