Black line doesn't get drawn

[/EDIT]
The code below creates a white canvas, draws a circle and a rectangle on it and then writes the result.
Both the circle and rectangle have a fill defined to be red. If the stroke colour is anything except pure black then it is drawn around the perimeter of the square and circle. But if the stroke colour is pure black it isn't drawn.
A bug, or am I missing something?
