Creating a Cocoa GUI window with NodObjC, with a proper Menu, dock icon, and NSApplicationDelegate.

var $ = require('NodObjC')

$.import('Cocoa')

var pool = $.NSAutoreleasePool('alloc')('init')
  , app  = $.NSApplication('sharedApplication')

app('setActivationPolicy', $.NSApplicationActivationPolicyRegular)

var menuBar = $.NSMenu('alloc')('init')('autorelease')
  , appMenuItem = $.NSMenuItem('alloc')('init')('autorelease')

menuBar('addItem', appMenuItem)
app('setMainMenu', menuBar)

var appMenu = $.NSMenu('alloc')('init')('autorelease')
  , appName = $('Hello NodeJS!')
  , quitTitle = $('Quit ')('stringByAppendingString', appName)
  , quitMenuItem = $.NSMenuItem('alloc')('initWithTitle', quitTitle
                                        ,'action', 'terminate:'
                                        ,'keyEquivalent', $('q'))('autorelease')
appMenu('addItem', quitMenuItem)
appMenuItem('setSubmenu', appMenu)

var styleMask = $.NSTitledWindowMask
              | $.NSResizableWindowMask
              | $.NSClosableWindowMask
var window = $.NSWindow('alloc')('initWithContentRect', $.NSMakeRect(0,0,200,200)
                                ,'styleMask', styleMask
                                ,'backing', $.NSBackingStoreBuffered
                                ,'defer', false)('autorelease')
window('cascadeTopLeftFromPoint', $.NSMakePoint(20,20))
window('setTitle', appName)
window('makeKeyAndOrderFront', window)

// set up the app delegate
var AppDelegate = $.NSObject.extend('AppDelegate')
AppDelegate.addMethod('applicationDidFinishLaunching:', 'v@:@', function (self, _cmd, notif) {
  console.log('got applicationDidFinishLauching')
  console.log(notif)
})
AppDelegate.register()

var delegate = AppDelegate('alloc')('init')
app('setDelegate', delegate)

app('activateIgnoringOtherApps', true)
app('run')

Results in:

boom! better irc client here we come

the last line > app('run') > results in a "bus error 10".
So What do I wrong?
I am on a quite new MacBookPro, Mountain Lion, latest versions of node and nodObjC.

so I could narrow it. It is related to AppDelegate.addMethod(). without that code, it works at least without crashing with a "bus error 10". Any ideas?
