[vtkusers] Crash in vtkImageViewer2 when Input is changed

[itkvtk123 at gmx.net]

---------------------
What do I want to do:
---------------------

Display image serie "A" using vtkImageviewer2.
When the forward one frame button (vtkPlaybackWidget) is pressed, display image serie "B".


---------------------
Problem:
---------------------

When forward one frame button is pressed and intensity windowing is changed afterwards, the program crashes.
(Even if image serie "A" is EXACTLY the same as image serie "B").

The crash happens in:

itkvtkimageexportbase.cxx, line 188/189

void VTKImageExportBase::UpdateInformationCallbackFunction(void* userData)
{
  static_cast<VTKImageExportBase*>
    (userData)->UpdateInformationCallback();
}
