Hi experts,  
I try to view a vtk file saved with python (nighres.save\_mesh), paraview can load it, but when I try to view the file, it breaks off. Can anyone tell me how to fix the problem? ( paraview version: 5.7.0-MPI-Linux-Python3.7-64bit)

Thanks in advance.  
Jewel

Hi @Jewel

ParaView is not able to read this file, there is an error in it:

```auto
POLYGONS 8934 35736 
3 35736 -9223372036854775808
3 92 93 

```

But ParaView should not crash in this case, I’ve submitted a fix for the crash here:
