I just installed xfce4 v4.2.3.2 on my Arch Linux box. I can change the settings
while logged in as root. But when I log into a non-root regular user account,
nothing happens when I click on the Settings icon on the Panel.

Also I see an error when I exit xfce4 -- Critical error cannot save settings.

I tried to delete my .config file in my home folder but that made no difference. 

FYI - Pernissions looked good anyway...

Directories were drwx and files rw for owner rob and group users. But when I log
into rob, startxfce4 and try to change settings nothing happens.

Next I uninstalled xfce4-goodies and xfce4. Then I manually deleted the .config
and .cache directories in the home folders for root and my regular user account
"rob". Then I installed xfce4 and xfce4-goodies.

Same problem. Cannot save settings when using my non root account rob.

I also see the following error messages --

I believe all this trouble started after I installed xscreensaver. 
So I just uninstalled xscreensaver. No difference. I still have the same problem..

I am also seeing some other error messages:
