Cause of the Problem
From OS log message, we see the problem happened due to wrong permission on the file /tmp/gconfd-oracle. It is needed to lock the directory /tmp/gconfd-oracle exclusively but because of 777 permission linux can't lock the file and so gconfd can't use it.

Solution of the Problem
The solution of the problem is give 700 permission and change ownership on the folder /tmp/gconfd-$USER.
If user is root then just do following,
#chmod 700 /tmp/gconfd-root/
#chown -R root:root /tmp/gconfd-root/
Now exit the window and re-login.

You can also try by removing /tmp/orbit- and then restarting X window.
#rm /tmp/orbit-root
