Trouble creating hdf5 dataset

[Nathan Lai]

This could be an issue with my hdf5 install but thought I would see if anyone had gotten a similar error. This occurs when Enzo gets to the data dump: 

DATA dump: dumpdirname=(./DD0000) == unixresult=0
HDF5-DIAG: Error detected in HDF5 (1.10.8) thread 1:
  #000: ../../../src/H5Ddeprec.c line 118 in H5Dcreate1(): name parameter cannot be NULL
    major: Invalid arguments to routine
    minor: Bad value

Any help is appreciated, thanks!

I suspect this is occurring because a field has been set with a NULL DataLabel. Check the initialization code to make sure all of the DataLabels are initialized with meaningful names.
