[jitsi-users] usage of Jitsi with TOR

independent of the usefulness to chat via TOR or not (there has been as
discussion some time ago in the forum) I tried to connect Jitsi via TOR
but failed:

starting Vidalia, TOR connects
changing global proxy in Jitsi to SOCKS5, server, port 9050,
checking box "DNS proxy" (which is there described for usage with TOR)
restart Jitsi
Jitsi cannot connect

any hints?
