When saving a new product, on a new Opportunity I receive this error:

common.exception.FieldIntegrityException: java.sql.SQLException: ORA-20067: ORA-06512: at "GRUMPY.GUTIL", line 42 ORA-06512: at "GRUMPY.SOPPLINEITEM", line 1091 ORA-06512: at line 1 : {call sOppLineItem.update_opplineitems(?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?)})}

There's no (active) triggers or validation rules on the OpportunityLineItem object. Cannot explain this. Below is a screenshot
