Hmm, does VDR assume ownership of menus it gets passed, ie. does it nuke
them when it doesn't need them anymore? That it should not do, but it's
not too easy to find out what really happens. Should every menu added with
AddSubMenu() be allocated on the fly?

Same goes with strings, VDR seems to assume ownership of a lot of strings,
resulting in quite a few unnecessary core dumps.
