I've been using Jitterbug for a couple of weeks now as my bug database for Mailman and JPython. So it was easy enough for me to set up a database for Python bug reports. Guido is in the process of tailoring the Jitterbug web interface to his liking and will announce it to the appropriate forums when he's ready.
In the meantime, I've created YAML that you might be interested in. All bug reports entered into Jitterbug will be forwarded to email@example.com. You are invited to subscribe to the list by visiting
