Aha, this in particular is a bug in Node.cs.  Uri doesn't have this
problem, afaics, as it has no == overloading (it probably should!)

Try these implementations for Node and see if they help:

		public static bool operator == (Node n1, Node n2)
		{
			if (Object.Equals (n1, null))
				if (Object.Equals (n2, null))
					return true;
				else
					return false;

			return n1.Equals (n2);
		}

		public static bool operator != (Node n1, Node n2)
		{
			if (Object.Equals (n1, null))
				if (Object.Equals (n2, null))
					return false;
				else
					return true;

			return !n1.Equals (n2);
		}
