I wrote a tool that will import bugs from Bugzilla into either Mingle and/or Trello (two project management tools used by some teams at the Wikimedia Foundation). The mobile web team was finding it difficult to keep track of two separate tools - one for new feature development, the other for tracking bugs, so Bingle helps bridge the gap and allows us to focus on one tool. This has had the side effect of keeping visibility of reported bugs high and has made it easier for us to quickly prioritize incoming bugs against existing work, and quickly respond to open issues.
You can find the code and some rudimentary usage instructions here: https://github.com/awjrichards/bingle
I hacked this together rather quickly - expedience was my goal rather than perfection, so it's not well documented, a little quirky, and there's a lot of room for improvement. I've been sitting on it for a while, hoping to make improvements before announcing it, but I have not found the time to make the changes I would like (eg for it to use the Bugzilla API rather than Bugzilla atom feeds). So, I invite anyone interested and willing to fork it, and pitch in and help make it awesome :)
