Bazaar is a distributed version control system that enables easy collaborative development. One of Bazaar's strengths is its adaptibility to different work flows.

developing Trac(http://trac.edgewall.org/) and its plugins(http://trac-hacks.org/). Look at the more complex ones like the discussion plugin(http://trac-hacks.org/wiki/DiscussionPlugin). Then look up the Trac APIs(http://www.edgewall.org/docs/branches-0.12-stable/epydoc/trac-module.html) it uses and understand the component model(http://trac.edgewall.org/wiki/TracDev/ComponentArchitecture).

Why Trac?

I think Trac is one of these projects which show how to use Python's beautiful features in the most sensible way. It's relatively easy to get started and you will get the important abstractions and concepts very fast. Plus, Trac is a really cool development tool and I'm sure sooner or later you'll use it for another project of yours.
