On ParaView master server always crash when launched using mpiexec -n X and when applying the Redistribute Dataset Filter.

The behavior was still correct in the release of PV 5.9.1.

Step to reproduce :

• Connect to a pvserver launched with multiple ranks
• Create a Sphere
• Create a redistribute dataset filter
• Apply
• Crash

I also tried to replicate using only VTK and the following code also crash (but since I'm unsure of my skills using MPI in VTK I didn't open the issue in VTK) :

vtkNew<vtkMPIController> controller;
controller->Initialize(&argc, &argv);
controller->SetCommunicator(vtkMPICommunicator::GetWorldCommunicator());
vtkMultiProcessController::SetGlobalController(controller);

vtkNew<vtkSphereSource> source;
source->Update();

vtkNew<vtkRedistributeDataSetFilter> rdsf;
rdsf->SetInputConnection(source->GetOutputPort());
rdsf->SetController(controller);
rdsf->Update();
