[vtkusers] problem with multi-component arrays

[Dominik Szczerba]

I am doing something as simple as:

nbs->SetName("MyName");
nbs->SetNumberOfComponents(NC);
nbs->SetNumberOfValues(NV);
output->GetCellData()->AddArray(nbs);
output->Squeeze();

in my vtkUnstructuredGridAlgorithm class. I am not even filling it,
nor accessing it, just appending to output. It only works for NC=1,
anything more leads to crashes of the type listed below.
Looks like VTK has a problem with multicomponent arrays - or did I
miss something?
