ListBox´s items icon not being drawn

Hello there

I´ve facing a problem with the listbox´s items icon. On Mac they don´t get drawn as you can see in the animation below. It is very strange if you keep clicking the button you´ll see that some get drawn other doesn´t.

if you see the animation above when I make active the listbox the icons get drawn. I´ve tried hard to fix this problem trying to force an update on the listbox but nothing seems to help.

Here is the sample test code as well as the icon just put it in the desktop.

    var img = Folder.desktop.fsName+"/icon.png";    var items = ["One","Two","Three","Four","Five","Six","Seven","Eight","Nine","Ten"];       var win = new Window("dialog","Tester",[0,0,300,400]);           var lb = win.add("listbox",[0,0,300,370],[]);           var btn = win.add("button",[0,370,300,390],"Update List");        btn.onClick = function(){                                lb.removeAll();                                for(i = 0; i<items.length; i++){                                    var item = lb.add("item",items[i]);                                    item.image = img;                                }                             }          win.center();    win.show();

By the way this only happens on a mac (AE CC ,2014, 2015), on pc it works fine.

Any help would be really appreciated.

Thanks
