Missing index

Hi

I'm running this

declare @tableName nvarchar(500) 
declare @indexName nvarchar(500) 
declare @indexType nvarchar(55) 
declare @percentFragment decimal(11,2) 

declare FragmentedTableList cursor for 
 SELECT OBJECT_NAME(ind.OBJECT_ID) AS TableName, 
   ind.name AS IndexName, indexstats.index_type_desc AS IndexType, 
   indexstats.avg_fragmentation_in_percent 
 FROM sys.dm_db_index_physical_stats(DB_ID(), NULL, NULL, NULL, NULL) indexstats 
   INNER JOIN sys.indexes ind ON ind.object_id = indexstats.object_id 
        AND ind.index_id = indexstats.index_id 
  WHERE 
-- indexstats.avg_fragmentation_in_percent , e.g. >30, you can specify any number in percent 
   indexstats.avg_fragmentation_in_percent > 5 
  AND ind.Name is not null 
  ORDER BY indexstats.avg_fragmentation_in_percent DESC 

    OPEN FragmentedTableList 
    FETCH NEXT FROM FragmentedTableList  
    INTO @tableName, @indexName, @indexType, @percentFragment 

    WHILE @@FETCH_STATUS = 0 
    BEGIN 
      print 'Processing ' + @indexName + 'on table ' + @tableName + ' which is ' + cast(@percentFragment as nvarchar(50)) + ' fragmented' 

      if(@percentFragment<= 30) 
      BEGIN 
            EXEC( 'ALTER INDEX ' +  @indexName + ' ON ' + @tableName + ' REBUILD; ') 
       print 'Finished reorganizing ' + @indexName + 'on table ' + @tableName 
      END 
      ELSE 
      BEGIN 
         EXEC( 'ALTER INDEX ' +  @indexName + ' ON ' + @tableName + ' REORGANIZE;') 
        print 'Finished rebuilding ' + @indexName + 'on table ' + @tableName 
      END  
      FETCH NEXT FROM FragmentedTableList  
        INTO @tableName, @indexName, @indexType, @percentFragment 
    END 
    CLOSE FragmentedTableList 
    DEALLOCATE FragmentedTableList

comes back with  IndexName 

PK_REVISION_INFO 

but 

Msg 1088, Level 16, State 9, Line 1
Cannot find the object "revision_info" because it does not exist or you do not have permissions.

when i look through the GUI interface I see index PK_REVINFO_CAA3212334
