Hi Ronald,
thanks for the clue. I think I've localised the problem.

This script shows the 10.9 NSView has a backgroundColor method.

from AppKit import NSView, NSColor
class MyView(NSView):
    def init(self):
        self = super(MyView, self).init()
        self.backgroundColor = NSColor.lightGrayColor()
        return self
    
print MyView.alloc().init()

On 10.8.4:

On 10.9 (13A558):
