[vtkusers] vtkImageExportToArray + VTK4

[Mathieu Malaterre]

Hi everybody,
    Does anyone of you try vtkImageExportToArray with VTK4 (in fact cvs from today). Because I
get a core dump with only:


from vtkpython import *
from vtkImageExportToArray import *

edgemap = vtkPNMReader()
edgemap.SetFileName("images/earth_edge.ppm")

a = vtkImageExportToArray()
a.SetInput(edgemap.GetOutput())
a.GetArray()


and here is the output of gdb:


Program received signal SIGSEGV, Segmentation fault.
