Hi,

with every Xcode project template involving Python it is enough to add 
an

import Quartz

to any python file to hang the application with the icon jumping in 
the dock.
From logs on the console it seems that the application isn't able to 
connect to the window server

_RegisterApplication(), FAILED TO establish the default connection to 
the WindowServer, _CGSDefaultConnection() is NULL.

exactly the same happens building with py2app and the -A (alias) 
option enabled, instead py2app without the -A option builds an 
application who can happily connect to the windowserver.
