gnome error message "OAFIID..."

Gnome Login Error The panel encountered a problem while loading "OAFIID ..."

---

Code:

sudo apt-get update
sudo apt-get install ubuntu-desktop gdm
sudo /etc/init.d/gdm start

This installs any gnome apps that might have gotten screwed up during the installation of other software.

Problem:
The panel encountered a problem while loading "OAFIID:GNOME_MixerApplet"
Failed to resolve, or extend '!prefs_key=/apps/panel/profiles/default/applets/mixer/prefs;background=none:;orient=down;size=x-small;locked_down=false
Solution:
just try to install some packages. (Re)install "gnome-applets" (and its dependencies "gnome-applets-data")
sudo /etc/init.d/gdm stop
sudo aptitude reinstall gnome-applets

Or
aptitude search applet | more
then:
aptitude reinstall [any applet preceded by a v or an i in previous step]
This essentially reinstall all the applets on the system.
