[Paraview] VRML File crashing ParaView 4.1

[Michael Jackson]

The files from this VTK bug report will crash ParaView:

http://paraview.org/Bug/print_bug_page.php?bug_id=1624

I am using "Instant Player" by Fraunhofer-Gesellschaft version 2.3.0 to view all the files that ParaView crashes on. ParaView will load simple VRML files but I think it may be the IndexedFaceList that is the problem?

The last few lines of the crash log are attached at the the bottom.
