[Paraview] Custom plugin reader with time series

[Dominik Szczerba]

Attached below. The line in my code (HDF5Reader.cxx:493) is:

status = H5Dread(dataset, H5T_NATIVE_INT, H5S_ALL, H5S_ALL, H5P_DEFAULT, 
(int*)data);

I am able to reproduce that this happens if and only if the underlying 
hdf5 dataset is chunked.
