DBMS_MVIEW.REFRESH调用导致ORA-01422错误

Question

I performed full database import into existing database with identical structure. After this, call the DBMS_MVIEW.REFRESH procedure cause ORA-01422 error. For example:

begin
 DBMS_MVIEW.REFRESH('SCHEMA_NAME.T_TOP_FRESH_COMMENTS');
end;

Error: ORA-01422 exact fetch returns more than requested number of rows
ORA-06512: at "SYS.DBMS_SNAPSHOT", line 2563
ORA-06512: at "SYS.DBMS_SNAPSHOT", line 2776
ORA-06512: at "SYS.DBMS_SNAPSHOT", line 2745
ORA-06512: at line 2

Select bellow returns single row:

select * from dba_registered_mviews t where t.name = 'T_TOP_FRESH_COMMENTS'

What do errors cause? How can I fix that? Thanks!

UPD:
Materialized view select doesn't cause error. The same error repeated for others materialized views. Script for creating view is listed below:

CREATE MATERIALIZED VIEW T_TOP_FRESH_COMMENTS
REFRESH FORCE ON DEMAND
AS
SELECT ROWNUM AS order_comment, id_comment, date_refresh
  FROM (  SELECT c.id_comment, MAX (h.updated) date_refresh
               FROM    t_comment_user c
                 INNER JOIN t_comment_history h  ON c.id_comment = h.id_comment
           WHERE c.published = 'T' AND h.published = 'T' and h.updated is not null GROUP BY c.id_comment
        ORDER BY date_refresh DESC)
 WHERE ROWNUM <= 10;

UPD1: I ran completed refresh and recieved the same error:

begin
  DBMS_MVIEW.REFRESH('SCHEMA_NAME.T_TOP_FRESH_COMMENTS','c');
end;

I recreated materialized view with REFRESH COMPLETE and this didn't help too. I tried to purge view log. It is didn't help:

begin
dbms_mview.purge_log('SCHEMA_NAME.T_COMMENT_HISTORY',99999,'delete');
end;
