dependancy not found (apt-get)

[Jor-el <jorel@austin.rr.com>]

Hi,

	I am trying to use my apt preferences setup to install "straw"
from unstable onto my stable system. Here is what I get :

trillian:/etc/apt# apt-get install -t unstable straw python-gnome2
python2.2-gnome2 libnautilus2-2
Reading Package Lists... Done
Building Dependency Tree... Done
Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

Sorry, but the following packages have unmet dependencies:
  libnautilus2-2: Depends: libgnome-desktop-0 (>= 2.0.3) but it is not
installable
E: Sorry, broken packages
trillian:/etc/apt# apt-get install -t unstable straw python-gnome2
python2.2-gnome2 libnautilus2-2 libgnome-desktop-0
Reading Package Lists... Done
Building Dependency Tree... Done
Package libgnome-desktop-0 has no available version, but exists in the
database.
This typically means that the package was mentioned in a dependency and
never uploaded, has been obsoleted or is not available with the contents
of sources.list
E: Package libgnome-desktop-0 has no installation candidate

	(1) What does this mean and (2) Is there hope for me?

Thanks,
Jor-el
