Ubuntu 11.10 - Cannot add new item when editing main menu

I still use the old school "Main Menu" editor AKA Alacarte to create new application launchers. Unfortunately, there is a bug that means that alacarte doesn't know about all of it's dependencies. This means that if you just install alacarte, and run "Main Menu", most of the buttons (including New Item) don't work. The solution is to manually install gnome-panel as well e.g.

sudo apt-get install alacarte gnome-panel
