  Great that its not a bug. Sounds like a great candidate for an

> Shannon reports he suspects a logic error in Eigencuts since it evidently does not produce exactly the expected results. It passes all current unit tests so we need to characterize the results differences and produce a test for it. Marking for 0.5 for now though we will fix it as soon as possible.
