Bug Description

Using the API, when I try to addTask on a bug that already has a task for that project, it oopses like OOPS-1174S4:

  IntegrityError: duplicate key value violates unique constraint "bugtask__product__bug__key"

It would be nice to have a proper error instead of this oops.

The error message could be a bit better, but other than that there's not much we can improve.

On the website, the target of the new bugtask is validated with valid_upstreamtask(). This happens in ChooseProductStep.validateStep. Since the validation code is in the view, not the model, it's not run when the same thing happens on the web service. Move the validation code into the model (this is the part I don't know how to do) and use webservice_error() or expose() on the exception raised when this error occurs.

I think leonard may already have fixed this.
