Nautilus has no installed viewer capable of displaying directories ("/")

[Oxyde <cskeogh bigpond net au>]

Hello nautilus-list,

I am using Gnome 2.2 on Sun sparc solaris 2.6, but I am unable to get 
nautilus to run. It builds successfully, but when I run nautilus I 
receive a dialog:

'Nautilus has no installed viewer capable of displaying "/"'

and...
'Nautilus has no installed viewer capable of displaying "/home"'
'Nautilus has no installed viewer capable of displaying "/home/keogh"'
'Nautilus has no installed viewer capable of 
displaying "/home/keogh/.gnome-desktop"'

I am using nautilus 2.2.3.1. The exact same message results when I have 
tried nautilus 2.2.1, 2.2.0.2, 2.0.8 and 2.0.7.
I am using gnome-vfs 2.2.4 and have tried 2.2, 2.0.4 and 2.0.2.
I am using gnome-mime-data 2.3.0 and have tried 2.2.0, 2.0.1 and 2.0.0.

Perhaps one of my packages is broken?
Is there a configuration file missing / broken?
Which file tells nautilus how to read directories?

Thanks in advance,

Craig Keogh
