Oracle error with no helpful message

A user clones an opportunity with products and the following error is reported:

java.sql.SQLException: ORA-20067: ORA-06512: at "GRUMPY.GUTIL", line 42 ORA-06512: at "GRUMPY.SOPPLINEITEM", line 696 ORA-06512: at line 1

There is no message to tell me what error occured. Also, I looked at the debug log and did not find any indication of an error there.
