Well, I am interested in the values.  The problem I am having is that I
don't know whether the array I've just recursed into is empty or not.
And it's the fact that when the array is empty it's invalid is why I am
triggering failed assertions.  I think just adding a return value to
dbus_message_iter_recurse() that's basically equivalent to
dbus_message_iter_init() would work.
