Greetings - I'm running into a problem with Durus being unable to pickle
dates.

Environement:
- latest released Durus
- Python 2.3, 2.4
- standard datetime but with Stuart Bishop's pytz tzinfo classes)
http://pytz.sourceforge.net/

Can you suggest where I might continue digging base on this:

->> commit()

    self.pickler.dump(obj.__getstate__())
