This is a problem with the binary reader in VTK.  If you comment out all 
the settings you initialize in the list_plot3d.py you'll get garbage 
results and it looks like my hooking up the results of this entire 
process breaks things with the rest of the pipeline.  Almost always 
segfaults are due to VTK related issues.

I'll look at doing one of the following, either popping up a UI so you 
can set the properties before the files is loaded or looking at the 
error code to defer creation of the property.  This is a bug.  Thanks 
for reporting it.  Hopefully I'll fix it soon.

cheers,
prabhu
