DBus ERROR - No Reply

Binary package hint: nautilus-cd-burner

lsb_release -rd:
Description: Ubuntu hardy (development branch)
Release: 8.04
BETA 1
new install on sda, all updates applied, "normal" installation

libnautilus-burn4 2.22.0 (runtime library) installed.

laptop:
Dell Vostro 1400 with built in:
DVD+-RW DS-8W1P

1) when I insert blank media NO "write-2-dvd/cd" dialog pops up.
    no automatic program is launched ......

2)
(see screenshot)

i open nautilus and choose GO-> CD/DVD Creator
OR
i open Places-> CD/DVD Creator

with or without a blank media inserted -> a Nautilus window appears but i can't add any files, it "stays" in discovery mode......
after some time the following errormessage is displayed:

Couldn't display "burn:///".
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.
Please select another viewer and try again.

after that every new try of it just displays the errormessage after some time but never again the original nautilus window.
you have to log off/on to get the frozen window again.

3)
I have a network drive at home, western digital, prebuilt with an 500GB HD, connected via 100MBit lan.
it is discovered under Networks -> Workgroup (windows) -> Shared Files and gets automatically mounted on the desktop
as expected. after working some time with it and then pausing the network drive goes into "quiet or standby" mode.

under win-xp/2000/98 it's no problem to wake it up after a new file operation was issued.

ubuntu: alpha5,6 and now beta1: it does NOT wake up, it cannot be reached anymore i get the same error as above:
Couldn't display "Shared Files on WD Netcenter".
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.
Please select another viewer and try again.

if I wake up the hd with windows, ubuntu still does not find it. only a reboot and re-mount solves the problem until it freezes again after a few minutes.

update: i changed networks (from work: only http and websense active, no access to online repositories ) to my homenetwork (normal broadband with minimal firewall) and applied 43 updates to the beta.
now cd/dvd creator works.

the error with the network drive only happens after x amount of time, i will observe that further.
