Variant< std::vector<T> > is for arrays, not tuples:
http://library.gnome.org/devel/glibmm/unstable/classGlib_1_1Variant_3_01std_1_1vector_3_01T_01_4_01_4.html#_details

I guess it would be nice to have sometime more strongly typed than
VariantContainerBase for tuples. Maybe we could use Variant<
std::vector<T> > for both somehow. But for now, I suggest that you just
use VariantContainerBase.

In fact, please test glibmm 2.27.99.1, which I just released, to see if
the new API makes it easier.
