OS Authentication login gives ORA-06512 and ORA-01400 errors when creating new test definitions. (4264672)

When connected as an OS Authentication user and trying to create a new test definition ORA-06512 and ORA-01400 errors occur.

To log in with OS Auth in Code Tester both user and password fields blank were left blank.

The program started up fine.

Then under Edit | New Test Definition the following was selected:

a) Owner selected: <OS Auth user><os></os>
b) Package selected: <some package><some></some>
(valid status, etc)
c) Clicked OK

Get the following error:
