problem when upgrading to FC4

[Steve Blackwell <steve j blackwell l-3com com>]

I just upgraded from FC3 to FC4 and now when I log in I get 3 error  
dialogs from nautilus but no desktop icons.

The dialogs are:

1) Couldn't display "/". Nautilus has no installed viewer capable of  
displaying the file.

2) Couldn't display "/home/steve". Nautilus has no installed viewer  
capable of displaying the file.

3) "x-nautilus-desktop:///" is not a valid location.

I tried moving

./.nautilus
./.gconf/apps/nautilus
./.gnome2/nautilus-scripts

to no avail.

ps shows that nautilus is running:
nautilus --no-default-window--sm-client-id default3

Nautilus is version nautilus-2.10.0-4 and eel is eel2-2.10.0-2.

Any insightt would be appreciated.
Thanks,
Steve.
