Unable to get the execution plan when using dbms_sqltune (11gR2)

Question

Hi,
Database version: 11gR2
I have a user A that is granted privileges to execute dbms_sqltune.
I can create a task, excute it and run the report.
But, when I run the report I get the following error:
SQL> show user
USER is "A"
SQL> set long 10000 longchunksize 10000 linesize 200 pagesize 000
select dbms_sqltune.report_tuning_task(task_name => 'MYTEST') from dual;SQL>

It seems there a missing privileg for dislaying the execution plan.
As a workaround, this is solved by granting select any dictionay (which I don't want) to the user A.
Does someone have an idea about what privilege is missing?
Kind Regards.

Hi,
SELECT ANY DICTIONARY system privilege provides access to SYS schema objects only => which you are using as workaround
SELECT_CATALOG_ROLE provides access to all SYS views only.==> Safe option
SQL> grant SELECT ANY DICTIONARY to test;
Grant succeeded.
SQL> conn test/test
Connected.
SQL> select count(*) from  sys.obj$;
  COUNT(*)
     13284
SQL> conn /as sysdba
Connected.
SQL> revoke SELECT ANY DICTIONARY from test;
Revoke succeeded.
SQL> grant SELECT_CATALOG_ROLE to test;
Grant succeeded.
SQL> conn test/test
Connected.
SQL> select count(*) from  sys.obj$;
select count(*) from  sys.obj$
