A thoughtless fix is easy in XContainer.cs to have ReplaceNodes() like:

        public void ReplaceNodes (object content)
        {
            var e = XUtil.ExpandArray (content);
            object [] arr = new object [e.Count ()];
            int i = 0;
            foreach (var o in e)
                arr [i++] = o;
            RemoveNodes ();
            Add (arr);
        }

but it is rather likely about issue in having iterator results stored
somewhere, regardless of the actual tree node status during operations (in this
case the "content" nodes are supposed to exist in the tree during the replace
operation, but they in fact don't because of RemoveNodes() operation).

I'll try to find possibly better solution when I get back my windows
environment (which should be soon).
