Attempting to migrate from Poi 1.0rc2 svn/unreleased build 2 to 1.1 rc 2. When running the archetype_tool schema update I end up with the following error:

TypeError: can't pickle code objects

Then I tried to update each piece of Poi once at a time. It worked for the first three (Poi.PoiIssue, Poi.PoiPscTracker, Poi.PoiResponse) once I got to updating the schema for Poi.PoiTracker I ended up with the same error. Here is the traceback for it:
