<br />
<br />
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).<br />
What I suspect is I'm having troubles in DBus functionality, but I don't know how to debug and repair it.<br />
<br />
Anybody can help?<br />
<br />
TIA<br />
