No Nautilus Side Panel (F9) in just one Fedora 14 install

[Robert Moskowitz <rgm htt-consult com>]

I have three systems running Fedora 14.  The most recent is my notebook, 
and that is the one with the Nautilus problem.

On any system I had had for years, one of the first things I do is to 
change Nautilus startup.  I start it, go into Edit -> Preferences, 
select List View, 'Open each folder in its own Window' (which seems to 
result with the behaviour I want that when I click on a folder, it does 
NOT open a new folder), and 'Include Delete command that bypasses Trash'.

I then close Nautilus and restart it to check things out.

Now I DON'T believe I did anything else this time, but I no longer have 
the Side Panel to view the directory tree, or the location line to get 
the directory listing, just the main window of the files and directories 
of where it is looking.  The View pull down does NOT offer F9 to open 
the side panel.

So I thought this is a config problem and I found a directory 
~/.gconf/apps/nautilus, I renamed this and opened Nautilus with the same 
view problems.

So where is my problem, some global config file?  If I open a terminal 
window, su -, the run nautilus, I get the same viewing problem as root.
