key = lua_tostring(L,-2) converts the object at -2 to a string; it used
to be a number, and this messes up the information that lua_next needs.

This is unfortunate. We'll try to improe this in 4.1.

You have to do something like this:
	val = lua_tostring(L,-1);
	lua_pushvalue(L,-2);
	key = lua_tostring(L,-1);
	lua_pop(L,2);
