[Paraview] Paraview 5.4.1 error message & freeze

[Sonya Davydycheva]

Cory,

The Glyph works just fine with my data.vtk and is very useful tool! It was
a good advice.

As to not-responding and freezing of ParaView: let me accumulate statistics
and then I will let you know.

I appreciate your help,

Sonya Davydycheva
