Don't see how this is a bug. It just as it is supposed to be. If your project does not have a specific start date, then it is a current or active project. And I am supposing its a sequential project. If the first action has a future start date, then none of the actions in the project can be a 'next action'. Thus this project is active (no start date means project has started and thus cannot be not pending), but with no doable action till the first action start date and thus has become stalled.
(Side note - All stalled projects are subsets of active projects)
