Abstract: SEVERAL RMAN CATALOG START WITH CREATES DUPLICATE CATALOG ENTRIES

PROBLEM:
--------
After several "RMAN  catalog start with "
we have several copies of the same backuppiece in our catalog which we can 
see
with "list backup;" and also "list backup summary;". This is defined 
behaviour.
    
However, when I now try to restore with that controlfile instead of a catalog 
I
receive 
  ORA-19693 backup piece "/opt/oracle/admin/mnt/HERMES2/bkp/..." is already
included.
 
 
Of course I went through the docs, but
- the delete command refuses to work because it finds several catalog (!)
  copies and it cannot address a single copy of a backup piece.
- the report and the list command do not give me an easy method of removing 
all
 the overcount copies. The problem is that they list several copies, e. g.
 copies 1 - 10, but I have to delete the single copies all by their backup 
piece
 key. 
 
 Because the backup pieces are not copied physically but just catalogued 
several 
 times they are not  physical copies but just "Duplicate catalog entries".
 
 
o Usually if you try to CATALOG a PIECE which is already in the Catalog 
  you should get:
  
    "no files found unknown to the database"
 
  But in customer case its cataloged twice !!! (not throwing the message)
´
o the second run should usually detect that the backuppiece: 'hngp1jl4_1_1'  
is
  already cataloged !!
  
  But it did not and catalog the file again, which leads to 2 entries
  in catalog for same Piece

Bug is over three years old and I cannot duplicate this behavior in 11g. Is 
this still a problem for the customer?
