The SPARQL is as follows.

WITH repos:fibo  
DELETE {[https://spec.edmcouncil.org/fibo/ontology/BE/Corporations/Corporations/PrivatelyHeldCompany](https://spec.edmcouncil.org/fibo/ontology/BE/Corporations/Corporations/PrivatelyHeldCompany) rdfs:label ?v}  
INSERT {[https://spec.edmcouncil.org/fibo/ontology/BE/Corporations/Corporations/PrivatelyHeldCompany](https://spec.edmcouncil.org/fibo/ontology/BE/Corporations/Corporations/PrivatelyHeldCompany) rdfs:label "person held company"}  
WHERE { OPTIONAL {[https://spec.edmcouncil.org/fibo/ontology/BE/Corporations/Corporations/PrivatelyHeldCompany](https://spec.edmcouncil.org/fibo/ontology/BE/Corporations/Corporations/PrivatelyHeldCompany) rdfs:label ?v} }

This used to work at 5.2.2 but following our upgrade to 5.3.1 produces the following error (from stardog.log). Removing the DELETE or the INSERT works fine: it's the combination that is the problem.

Hi Pete,

This problem was actually reported elsewhere a little while back and the fix should be in the next Stardog release!
