Segfault when .vti file contains duplicate data array name
Attaching a data file that comes from a Kitware customer, that when loaded into ParaView 5.12 or master, causes a segfault. Crash is inside the VTK reader.
We should not segfault on duplicate data array names - either abort data loading with a warning, or complete data loading with a warning, and ignore the duplicate data array name. Or possibly modify the name so it is not a duplicate.
