Wow, you're running a lot of very lighly-used code paths!  You actually
found a similar but totally separate issue from what I gather.  Thank
you immensely for the quick testing and bug reports!

Could you test the attached fix?

For those playing along at home, I think this will end up being needed
for 4.15 and probably all the backports.  I want to see if it works
before I submit it for real, though.
