GDM functions gone in XFCE after upgrade to ubuntu 12.04

Hi,

I ran into a problem with XFCE after upgrading to ubuntu 12.04:

Usually XFCE has rather basic desktop functions, e.g. does not show the contents of images in ~/Desktop as icons.

With ubuntu versions up to 11.10 this could be easily changed by starting

/usr/bin/nautilus --no-default-window

from the command line or simple by enabling to start the Gnome runtime environment after login in the XFCE session and startup settings. Worked well bevor 12.04

Now, it does not work anymore. Setting this option or starting nautilus from command line has no effect:

% /usr/bin/nautilus --no-default-window
Initializing nautilus-gdu extension
Shutting down nautilus-gdu extension

So there's something wrong. After all, that's the only idea of this option.

I tried to report this as a bug to ubuntu ( #994240 ), but the maintainer closed the bug as invalid because asking questions about how to configure software would not be legitimate bug reports. Which is nonsense in my eyes, because you could turn every bug report into a question about how to workaround and declare it as invalid. Furthermore, it is a functionality that was there, and now is gone. The XFCE option simply does not do it's job anymore.

However, if the ubuntu team insists on the kind of view that this is not a bug, just my inability to configure my desktop:

Can anyone tell me how to enable this?

Maybe it's the way I am clicking the check mark in the options menu in a wrong way?
