Materialized View, ORA-12008: error in materialized view refresh path

Question

I want to refresh a materialized view, but I get an ORA-12008 error.
Does anybody have an idea? I do not find any errors in my refresh statement.
CREATE MATERIALIZED VIEW scott.dummy_mv
  TABLESPACE test
  BUILD IMMEDIATE
  USING INDEX TABLESPACE idx_test
  REFRESH
     START WITH sysdate
     NEXT ROUND(SYSDATE)+5/24          
     WITH PRIMARY KEY
  ENABLE QUERY REWRITE
  AS
  SELECT KM.ID ID
          ,KM.USERNAME USERNAME
       ,KM.ABTID ABTID     
  FROM my_table KM
scott@orcl>desc dummy_mv
Name                                      Null?    Typ
ID                                        NOT NULL NUMBER(4)
USERNAME                                  NOT NULL VARCHAR2(30)
ABTID                                     NOT NULL NUMBER(4)
scott@orcl>
BEGIN
  SYS.DBMS_JOB.REMOVE(6579);
COMMIT;
END;
DECLARE
  X NUMBER;
BEGIN
  SYS.DBMS_JOB.SUBMIT
  ( job       => X
   ,what      => 'dbms_refresh.refresh(''"scott"."dummy_mv"'');'
   ,next_date => to_date('07.01.2009 05:00:00','dd/mm/yyyy hh24:mi:ss')
   ,interval  => 'ROUND(SYSDATE)+5/24              '
   ,no_parse  => FALSE
  SYS.DBMS_OUTPUT.PUT_LINE('Job Number is: ' || to_char(x));
COMMIT;
END;
scott@orcl>exec dbms_refresh.refresh('dummy_mv');
BEGIN dbms_refresh.refresh('dummy_mv'); END;

I get the same error:
scott@orcl>exec dbms_mview.refresh('dummy_mv','c');

I would first check the "query" information of the DBA_SNAPSHOTS/DBA_MVIEWS dictionary views if it reveals anything obvious.
But it looks more like an internal error while processing the refresh. You can get more information about the error by tracing the session. A "alter session set sql_trace = true;" before running the refresh should be sufficient. Disconnect afterwards and check the generated trace file for errors either using "tkprof" and checking the output or by manually searching for "err=" in the trace file.
Which 4-digit version of Oracle are you using?
