Hello Mark,

To read EnSight files without segfaulting on nfaced elements, while
waiting for full polyhedron support, you may try this modified version
of the VTK EnSight readers:
http://yvan.fournier.free.fr/paraview/nfaced/
They read nfaced elements as VTK_CONVEX_POINT_SET, which is nowhere near
as good as full polyhedron support, but still more useful than a
segfaulting application (I recently updated it to the main ParaView 3
CVS, though I should still add handling, or rather ignoring of g_nfaced
elements for EnSight SoS format files).

There is an older version of these modified files in the ParaView
bugtracker, but it seems to have gathered some dust.

Hoping this is useful.
