[Paraview] Xdmf segfault

[Utkarsh Ayachit]

Oops..I should really start reading what I type before hitting "send"
:). What I meant to say was this:

      Good catch. I am looking into this. "Your" fix "doesn't" suffice since it
      would result in the block selection from the state totally being
      disregarded. I'll get back to you soon.
