[vtkusers] QVTKWidget + vtkRectilinearWipeWidget

[florian]

Thanks for the info, i tried that but still cant get it working.

I used this example:
http://www.itk.org/Wiki/VTK/Examples/Cxx/Widgets/RectilinearWipeWidget
and wrote a minimal implementation using a qvtkwidget that causes the 
problem.

I hope anybody has an idea what causes this problem, because im 
completly stuck here :/

I would have uploaded the files, so they could be directly compiled, but 
I didn't know what methods are admissible.
