Proper Args for Window.setIconList()?

I'm back banging on this bit of code that puts together a doubly-linked list of Pixbufs for use as Window icons, etc. I assemble the list, check the integrity of the list and everything seems fine. Then I pass it to Window.setIconList() and get the errors shown below.

Does this function work as intended? Am I assembling the ListG wrong?

string[] images = ["images/airport_25.png",
                   "images/airport_35.png",
		   "images/airport_60.png",
		   "images/airport_100.png"];

ListG listG = new ListG(null);
		
for(int i; i < images.length; i++)
{
	string imageName = images[i];
	Pixbuf pixbuf = new Pixbuf(imageName);
	listG = listG.append(cast(void*)pixbuf);
}

// check list integrity
uint listLength = listG.length();
		
for(int i; i < listLength; i++)
{
	Pixbuf pixbuf = cast(Pixbuf)listG.nthData(i);
	writeln("data: ", listG.nthData(i), ", width: ", pixbuf.getWidth());
}

setIconList(listG);

Which results in these errors:
