Debugging Pyramid 1.3 applications with PyCharm

I can't debug Pyramid 1.3 applications on PyCharm with windows. In the past I've used Pyramid 1.2 on Mac, so I don't know which is it that's causing the problem.

I can debug other Python programs in this environment with PyCharm.

Here's the failure

Any ideas?  I have submitted a bug report.
