Update query using INSERT { ... } WHERE { FILTER (...) } causes crash
This update is rather useless, so this isn't a blocker or anything, but we should avoid the crash.
Run the attached script in a directory with the .ontology file and you'll see the crash.
Query:
INSERT { ?file a nautilus:File ; nautilus:starred true . } WHERE { FILTER(?file IN (<file:///home/sam/Desktop>))}Backtrace:
