[Paraview] How to save data to xmf format?

[David E DeMarle]

You are seeing a bug that was fixed after paraview 4.1 was released.
Specifically this VTK fix corrected it:

commit 0679bf4054088ee15408bcfda4b28539fb66bc1d
Author: Tristan Coulange <tristan.coulange at kitware.com>
Date:   Tue Feb 4 17:34:43 2014 +0100

    BUG: fix some xdmf writer crashes

    - Sets the number of output ports to 0, which avoid an error message in
      Paraview because the writer is used in a pipeline.
    - Manages a potential null pointer, avoiding a crash which occurs when
the
      user unchecks some blocks in Paraview for instance.

    Change-Id: I09c69bc6ac715bcb4297df4e2a012514a7817c57

Try a ParaView nightly build which you can get a binary for from the
download page, or build from source to obtain.
