The reason that this is happening is that vtkThreshold has really bad logic to determine if the input array is point or cell based.

Instead of using the number of values compared to the number of points, instead we should determine if the arrays is associated with cell data or point data.

on line 128 we should look at the association of the InputArrayToProcess, if that doesn't work we can brute force pointer comparison with the point and cell data arrays on the input data set.
