As per ML Note 175982.1 I would suspect it has something to do with
objects used in the data dictionary. You may have noticed there is a
corresponding type for each table.
You'll probably need to open an SR to pursue this further:
select * from kottd$
*
ERROR at line 1:
ORA-30732: table contains no user-visible columns
*ORA-30732: table contains no user-visible columns* *Cause:* An attempt was
made to query on a system table which has no user-visible columns.
*Action:* Do not query on a system table that has no user-visible columns.
