Yes, definitely 32-bit Python:
$ python
Python 2.7.1 (r271:86882M, Nov 30 2010, 09:39:13)
[GCC 4.0.1 (Apple Inc. build 5494)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> import platform; print platform.architecture()
('32bit', '')
My app works fine when run without py2app.

If you do import platform; print platform.architecture() what do you get? Does the program work properly when not built as an app? -Chris ___ Pythonmac-SIG maillist - Pythonmac-SIG@python.org http://mail.python.org/mailman/listinfo/pythonmac-sig unsubscribe: http://mail.python.org/mailman/options/Pythonmac-SIG

What you could try is to build using '--no-strip' and then use 'gdb ./dist/OpenSTV.app/Contents/MacOS/OpenSTV'. With some luck this gives a hint on what causes the crash. Are you by any change importing GUI code in a secondary thread? I've seen crashes in __CFInitialize before when Apple's frameworks get loaded on any thread that isn't the main thread.
