Again, the compiler is always right: you need to initialize your
GLib.Value. But the GetValue () function can't initialize that variable
itself; you need to create an non-null but empty GLib.Value, which
GetValue can then set.

	GLib.Value value = new Value ();
	sel.GetSelected (out model, out iter);
	model.GetValue (iter, 0, value);

You may also be interested in the GetValue (iter, column) function,
which returns an the Val property of a temporary GLib.Value, making your
code cleaner:

	sel.GetSelected (out model, out iter);
	object value = model.GetValue (iter, 0);
