Reset Ubuntu Panel

My Ubuntu 10.04 panel are not showing all the application icons that are currently running. It happened after an error occurred while opening my computer. Good thing the panel can be reset through the following terminal commands:

Unset all gnome settings:

gconftool --recursive-unset /apps/panel

Remove configuration files:

rm -rf ~/.gconf/apps/panel

Restart the Gnome panel:

pkill gnome-panel
