Happy you finally got your readyState=4, Tim! Thanks for your help
testing with Tabulator today.
Eric and I had already discussed error handling at lunch. There are
indeed 500s propagating from segfaults in the C++ wrapper. We also plan
to subclass the SPARQL expression walker to provide more granular ACL
evaluation.
I'm including below some server log to complement your client ;)

Repeatable.
Changing a comment string the same happens.
