The setup file looks fine. 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. Ronald
