Sorry, but only looking on MPI-2 page 61 and the new text above, 
I can not understand this item.

Looking also at
http://www-unix.mcs.anl.gov/~gropp/mpi/mpi-errata/discuss/errhandlers/ 
and there on the last mail
 
  |  I propose the following clarification be added to the errata:
  |  
  |  MPI_GET_ERRORHANDLER, MPI_{COMM,WIN,FILE}_GET_ERRORHANDLER behave as if a
  |  new error handler object is created.
  |  This provides behavior similar to that of MPI_COMM_GROUP.
  |  
  |  Rationale:  This case was overlooked in the MPI-1 document.
  |  
  |  Any objections?
  |  
  |  Bill

I see that someone has removed MPI_GET_ERRORHANDLER and the Rationale.
Looking at the text MPI-1, page 139, MPI_COMM_GROUP ...,
I can not understand the sentese 
"This provides behavior similar to that of MPI_COMM_GROUP".

It may be, that the text of this errata can be improved by someone
who is familiar with the content of this problem.

Thanks
Rolf
