I'm trying to visualize some medical data using ITK (2.8 and 2.6) + VTK 
(5.0.0-rc1 and 5.0.1) + KWWidgets. I took MedicalImageViewer example 
(from KWWidgets) and replaced code using vtkXMLImageDataReader with code 
performing reading a volume with ITK (I copied this part from another 
program that works fine). I haven't changed anything else. It compiles 
without errors and warnings but after running the program I get unhalted 
exception in vtkimagemaptowindowlevelcolors.cxx in line 364. Then I 
tried vtkDICOMImageReader and it works fine. I don't know what is wrong. 
I suspect that the problem is with connecting VTK and ITK pipelines and 
their cooperation with KWWidgets (vtkKWRenderWidget ???), because ITK 
and VTK without KWWidgets and also like I said VTK and KWWidgets work 
good. I don't know if this mailing list is proper to ask about help with 
this problem but I really need your help.

To connect ITK and VTK pipelines I use code from 
InsightApplications/Auxiliary/vtk but only one header file 
itkImageToVTKImageFilter.h and I even did not build Insight 
Applications. I got to know from InsightApplications Readme that Insight 
Applicatins (2.8.1) needs VTK version 4.4 but I use VTK 5.0.0-rc1 and 
also tried 5.0.1. In both cases I got the same unhalted exception. Maybe 
it is the reason why VTK, ITK and KWWidgets do not want to cooperate 
(KWWidgets needs VTK 5.0).
Could someone tell me if I am right.
Thanks in advance
