GNOME 3 - Gconf Error

[Manish Kathuria]

I am using the latest version of gnome shell (3.2.1-2) on Fedora 16
and many times a window appears with an error message saying  "GConf
error: Configuration server couldn't be contacted: D-BUS error: The
GConf daemon is currently shutting down."  The desktop session goes
haywire after that, the windows on the desktop screen appear broken
and their borders distort and many of the applications (like Gnome
Terminal) don't start.

Has anyone experienced something similar and found a fix for the same ?

Thanks,
