Ouch! ORA-01031: insufficient privileges ?

yesterday we hit a bug in 11.2.0.3:

if you grant various dbms_* packages to another user “with grant” option and try to pass through this grant with that user you may hit bug 13036331

simple test-case to confirm that you are affected:

create user blubb identified by "blubb";
create user blabb identified by "blabb";
grant connect,resource to blubb;
grant execute on dbms_lob to blubb with grant option;
connect blubb/blubb
grant execute on dbms_lob to blabb;

ERROR at line 1:
ORA-01031: insufficient privileges 

it seems that only 11.2.0.3 is affected. we already had a psu applied ( 11.2.0.3.1 ), so this does not help…
