Unfortunately, PyQt catches all exceptions and just prints them out.
I don't believe there's a way to change that behavior.
You can, however, override python's ctrl-c handler using the signal
module. Note: the handler won't be called until the python
interpreter gets control again. If what you're trying to do is just
kill the app quickly, then just restoring the default handler will
import signal; signal.signal(signal.SIGINT, signal.SIG_DFL)
As an alternative, you can try ctrl-\. On most unix systems, this
sends a sigquit which should kill the app immediately in all cases,
though you'll have to put up with core dumps. I don't know about
