Hi I'm aware this is a bit of a long shot, but maybe someone recognises this issue. I have a python application generated with pyobjc on OSX 10.8. - Stock python Python 2.7.2 (default, Oct 11 2012, 20:14:37) - presumably also a stock objc 2.3.2a0, (at /System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/PyObjC/objc/__init__.py) On 10.7 and 10.8 I can get a new window when I select New from the menu. On 10.9 (the current developer release) I get an exception, "cannot change a method" - see below. The app continues to run, but there isn't much of a traceback. Looking at the dump, I get the impression something goes wrong when NSDocumentController calls newDocument: My NSDocument subclass doesn't contain anything suspicious. I think I'm using up to date calls for reading and writing. Methods in my NSDocument subclass: init readFromURL_ofType_error_ writeSafelyToURL_ofType_forSaveOperation_error_ makeWindowControllers + a couple of callbacks for menus. I've tested this with two independent projects, both get the same exception. Any guesses would be welcome, thanks.
