Hi all,

 After an upgrade of a debian testing server I got freenx server broken. For a week now I have been struggling with this problemInstalling and uninstalling freenx many times.

 present situation is:
 1) Server running:
 # /usr/lib/nx/nxsetup --test

 As far as I understand there is a problem in retrieving values from DBus and hence in building the unique session-id (but I may be wrong).
 What I suspect is I'm having troubles in DBus functionality, but I don't know how to debug and repair it.

 Anybody can help?

 TIA
