Apparently the problem appeared with the 10.6.6 update, but it runs fine on many other such machines. I have asked the user all kinds of questions in this direction (screen/appearance etc.) but he says there is nothing unusual. Next I will try if it makes sense, in carbontrayicon.inc, to call statusItemWithLength with a different parameter (currently the parameter is NSSquareStatusItemLength). If all fails I will just make it so that the app doesn't try to use the tray icon any more if it has failed once. It really seems to be just this one machine.
