Sprint backlog items of type Bug and Work item type Bug on Scrum dashboard /Conchango work item template

As I've discussed earlier, we're using the episerver scrum dashboard and while testing today, I've found a small issue for my team

If you haven't used the dashboard, it's based on the conchango work item template and it have a number of work item types, for example product backlog item, sprint backlog item and bug.

Product backlog item: stuff on the product backlog

Sprint backlog item: tasks to be performed during the sprint

Bug: bugs or defects

When you set the sprint on a product backlog item, this becomes visible on the scrum dashboard (the column on the left side). You can do the same with a work item of type bug: it then becomes visible on the left column)

You can then click a product backlog item or a bug and select a number of tasks: one of these being create related bug. But here is the trick: this is not a work item of type Bug, this is a sprint backlog item marked as a bug. So if you use the reports over active bugs these bugs will not show up. Why? Well, if the bugs are a result of defects during production you will probably not that those show up in release notes and should not clog up the statistics: when you look at the bug reports these are bugs in production. In other words:
* If the bug never makes it to production, it will become a sprint backlog item of type bug
* If the bug is spotted as a part of delivered functionality, it should be reported as a work item of type Bug.

Hard to understand? Well, I know my way around the work item types by now so I can understand it but how can I possibly explain this to a new acceptance tester. And how should this person be able to know if it's a Bug or a Sprint Backlog item of type Bug? Another problem is that you cannot report Work items of type Bug using the Scrum dashboard: you have to use the web access or ordinarie Windows client.

And also, if you have reported a sprint backlog item of type bug during the sprint and the problem is not addressed, you must remember to create a linked work item of type Bug.

(And don't hit me, I didn't come up with this solution)
