I have similar problems, I have started a thread on the pyobjc-dev  
mailing list with my current findings: the problem seems related to  
importing the Quartz framework before Cocoa connects to the window  
server, in alias builds *only*. So for example, doing an 'import  
Quartz' before doing 'AppHelper.runEventLoop()' or  
'NSApplication.sharedApplication' will fail, but in alias builds  
*only*. So this definitely looks like a PyObjC/py2app bug to me so far.
