Suggest an open-source issue tracker, with github integration and kanban boards?

[Alec Taylor]

Started to build this on my own; then was like, hang on! - This is
probably something very commonly requested…

Can you recommend an open source project (or two) written in Python;
which covers multi project + sub project issue tracking linked across
github repositories?

[on the github side, want to be able to reference "commit <hash>
solved by patch from issue #"; fine to have that extra annotation only
present on my server]

Also would be perfect if it has kanban board support, issue
prioritisation and distribution/assignment amongst team members; as
well as related analytics.

Thanks for all suggestions! =)
