This is the expected behavior. This:

... fills a rectangle with top-right (assuming positive width and
height) corner (cellFrame.origin.x + cellFrame.size.width,
cellFrame.origin.y + cellFrame.size.height), while this:

fills a rectangle with top-right corner (cellFrame.size.width,
cellFrame.size.height). These are different rectangles;
cellFrame.size.width != cellFrame.size.width + cellFrame.origin.x .


You should probably ask questions like this discuss-gnustep, not
gnustep-dev. (Or, if you're fairly certain it's a GNUstep bug,
bug-gnustep.)
