Greg,

I think your change is just equivalent to mine, as far as the retain count is
concerned. But not copying something is always great.

The problem with your changes is that they als result in the the same
problems that I had after mine. When you start up Bean, create a new document,
close that and again start a new document. Now closing that from the close
icon in the window decoration will result in the following backtrace (windows
decoration drawn by GNUstep):
