Python Timer crashes the interpreter
===

I'm new here and this is my first question. I'm making a game in Python 3.2.3 and I've come to a problem where a Timer object sometimes crashes the interpreter after calling it's start() method (it happens like 50% of the times, there is always an error window saying that Python stopped working and had to be terminated). I've been simplifying my code so I could locate the issue and I've discovered that this very simple code crashes my interpreter:

    from threading import Timer

    def hello():
      print("hello, world")

    t = Timer(1.0, hello)
    t.start()

I've tried repairing my Python instalation, which didn't work. I'm running Python under Windows 7 and unfortunatelly haven't had a chance to try another operating system so far, so if anyone has any experience with this issue, I would appreciate any solutions to this. Thanks everyone.
