When performing an export / import using datapump or with the legacy exp / imp utilities, a bug can cause wrong privileges to be granted to users.
The circumstances under which the bug occurs seems to be that a privilege is given on one user with grant option and on a second user (or role) without grant option and that the object must be a schema procedural object (job, program, schedule, …).
I could reproduce this issue on 10.2.0.4, 11.2.0.2 and 11.2.0.3, so changes are that all versions since 10.2 (or even 10.1) are affected.

SYS.DBMS_UTILITY.EXEC_DDL_STATEMENT('GRANT ALTER ON "FDH"."TEST" TO "GRANT_TEST_USR2" WITH GRANT OPTION');
As you can see, all three grants on fdh.test are now including the “with grant option” clause, while only the grant to grant_test_usr should have been using the “with grant option”.
The privileges on the procedure are correct.
I have logged a case about this with Oracle, but no bug number is assigned at this moment
