nautilus network browsing broken after system upgrade (10.04 -> 10.10 beta1)

[Alex Popovskiy]

Binary package hint: nautilus

After system upgrade I can't get it working again (it worked fine in 10.04), now nautilus just says "Please wait while opening..." and after some time I get an error: "DBus error org.freedesktop.DBus.Error.NoReply: Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken.". But samba server is still ok, I can access my PC from windows hosts without problems/
