Not running within active session

Hi guys,
help needed there:
ubuntu-server 8.10, updated to today

I was installing ebox and this error message comes out:
Failed to contact configuration server; some possible causes are that 
you need to enable TCP/IP networking for ORBit, or you have stale NFS 
locks due to a system crash. See http://www.gnome.org/projects/gconf/ 
for information. (Details -  1: Not running within active session) at 
/usr/share/perl5/EBox/GConfModule.pm line 50.

Trying to spawn the server:
Failed to spawn the configuration server (gconfd): Failed to contact 
configuration server; some possible causes are that you need to enable 
TCP/IP networking for ORBit, or you have stale NFS locks due to a system 
crash. See http://www.gnome.org/projects/gconf/ for information. 
(Details -  1: Not running within active session)

Version of gconftool: 2.24.0

No messages in logs (empty files). Only root has the .gconf directory. 
Normal users do not have this directory (no gconf calls from users, 
that's ok, just fyi).

Last but not least: error message comes out beeing connected both 
directly or via ssh and it is a virtual mac

Please let me know what do you need more in order to help me.

Thanks in advance!
