Problem with DBMS_METADATA.GET_DDL and subpartitions

Question

I have problems with DBMS_METADATA.GET_DDL in a 11gR2 (11.2.0.3) database on Linux. The following example shows the problem:
CREATE TABLE Test_tbl
C1 NUMBER(14),
C2 NUMBER(14),
C3 NUMBER(14)
PARTITION BY RANGE (C1)
SUBPARTITION BY LIST (C2)
PARTITION Part1 VALUES LESS THAN (1000)
, PARTITION Part2 VALUES LESS THAN (2000)
CREATE INDEX Test_idx ON Test_tbl (C3) LOCAL;
When I execute
SELECT DBMS_METADATA.GET_DDL('INDEX','TEST_IDX') from dual;
on a 10g database (10.2.0.2.0) on Solaris Sparc and on a 11.1.0.7 on Windows, it gives the correct DDL statement within some seconds.
On the 11.2.0.3 database (Linux) it hangs forever.
SQL> SELECT DBMS_METADATA.GET_DDL('INDEX','TEST_IDX') from dual;
^CERROR:
ORA-01013: user requested cancel of current operation
This behavior only seems to occur in combination with local indexes and subpartitions.
Anyone any idea?
Thx, Carsten

^CERROR:
ORA-01013: user requested cancel of current operationWhy did you cencel this operation? Usually it takes time. If its taking more then it would be better to gather dictionary stats once.

Thx, CarstenI didn't get any problem in 11.2.0.1 database:
SQL> CREATE TABLE Test_tbl
  2  (
  3  C1 NUMBER(14),
  4  C2 NUMBER(14),
  5  C3 NUMBER(14)
  6  )
  7  PARTITION BY RANGE (C1)
  8  SUBPARTITION BY LIST (C2)
  9  (
10  PARTITION Part1 VALUES LESS THAN (1000)
11  , PARTITION Part2 VALUES LESS THAN (2000)
12  );
Table created.
SQL>
SQL> CREATE INDEX Test_idx ON Test_tbl (C3) LOCAL;
Index created.

SQL> SELECT DBMS_METADATA.GET_DDL('INDEX','TEST_IDX') from dual;
DBMS_METADATA.GET_DDL('INDEX','TEST_IDX')
  CREATE INDEX "SYS"."TEST_IDX" ON "SYS"."TEST_TBL" ("C3")
