Good news -- I found an easy fix. Instead of failing outright when

(scalar (scalar scalar))

is found because the internal data structures can't handle nested lists
following scalar data, I patched the reader to simply read the nested list,
discard it, print a warning, and continue reading the file.

You'll still see a warning pop up in paraview, but the file should still
read successfully as long as the unsupported list does not appear in a
field used for visualization.

The patch is here: https://gitlab.kitware.com/vtk/vtk/merge_requests/1598

If this is agreeable to everyone, we'll get it merged and incorporated into
a future release.
