Just today, Two compounded errors.
1) The SWOBJECT link to python seems to have died.
2) When the server produced that error message, it did it with a 200 return code, instead of an error code. So the tabulator ignores the problem and behaves as though the data has been written back.
This was working yesterday.
Could I have broken it by sending badly formatted SPARQL?
