parallel netcdf on BG, colons in filenames?

This program works on the NCAR blue gene system:

           implicit none
           include "mpif.h"
#include "pnetcdf.inc"
           integer stat, ierr, comm, ncid
           call mpi_init(ierr)
           stat = NFMPI_CREATE(MPI_COMM_WORLD, "wrfout_d01_2002-05-27_00_00_00" , NF_CLOBBER, MPI_INFO_NULL, ncid)
           print*,stat,ncid
           stop
           end
 
This one does not:

           implicit none
           include "mpif.h"
#include "pnetcdf.inc"
           integer stat, ierr, comm, ncid
           call mpi_init(ierr)
           stat = NFMPI_CREATE(MPI_COMM_WORLD, "wrfout_d01_2002-05-27_00:00:00" , NF_CLOBBER, MPI_INFO_NULL, ncid)
           print*,stat,ncid
           stop
           end

The output from this 2nd program is attached.

The only difference is colons characters in the file name.  Any ideas? (aside from the obvious, don't put colons in file names :-)
