Yes, I hit this problem months ago, but didn't have time to send the fix.
So I had to have "git revert 09d8b39563e84fc245d642182715a7e0e024b0f2" in my

Yes, it is true in that I don't really care about the output error message.

But then again. This error message can only happen if JSON::PP is not
installed, and my patch doesn't make it worse?

Oleg.
