[Paraview] XDMF HyperSlab hints or example needed

[Eric E. Monson]

I agree that there's something very screwy going on. I can sometimes  
load a slightly reformatted version of this, but only when I've just  
opened PV 3.4, and even then when I look in a spreadsheet view it's  
not showing the correct data (not jumping by 2 in last dim). If I  
"delete" and reload, it crashes. I tried another test set that's 3d to  
begin with, and got a lot of crashes, too.

Sorry I have to run, but wanted you to know that I'm seeing something  
very similar.
