Restore Ubuntu panels

It seems a common (or more frequent) issue with Ubuntu? I've been using Ubuntu for few months (in addition to other LINUX based OSes I've been using) and came across this issue in my Ubuntu 10.10 (Maverick Meerkat). At the start up it gives you some error messages saying "unable to load blah blah... " (on some desktop applets etc...).

It's relatively easy to restore them back to their original(default) settings though. Just run the below and the panels will be restored.

$ gconftool --recursive-unset /apps/panel
$ rm -rf .gconf/apps/panel
$ pkill gnome-panel
