There likely is no uncaught exception, since such should produce a 
visible stack trace, certainly if the app is run from a Command Prompt 

Victor Stinner is working on a module for 3.3 that will try to catch 
crashes and produce some report before everything is gone. It may be up 
on PyPI before that.
