Bingo.  If they are fully qualified table references
(owner.table_name) then the problem doesn't show up.

When I got hit, our application had a generic login
and used a "alter session set current_schema" on
the login trigger to give it access to tables of a given
schema. Our sql had no owner.table_name as we
wanted to be able to execute it against a different set
of tables by simply changing the login trigger.
Turned out to be a surprise party...
