Ok. Appended here.

I rolled back PA to 0.9.15 and retested and confirmed that 0.9.15 works
with everything else the same. After the -vvv output below is a second
one, this one from PA 0.9.15.

There was a lot more output on PA 0.9.15. Hopefully I didn't cut it too
short. I can capture it again if I did.
