RecursionError: maximum recursion depth exceeded in comparison


I don't have artifacts for this, so I didn't try to reproduce it.  Also
it doesn't seem very reproducible either, as other suites/architectures
didn't hit this crash in their last run.  Nonetheless, I figured I'd
file this for tracking (it sounds easy to check for RecursionError and
give up on the jsondiff comparator…).
