If you select an image and click on any button in the Colour Image Processing bundle a DataNode named "No Name!" is created.
If you select this new Node and click again on any button VTK errors with the following message appear:
"ERROR: In ..\..\..\source\VTK542\Rendering\vtkOpenGLTexture.cxx, line 179
vtkOpenGLTexture (1B14A390): No scalar values found for texture input!"
The new Nodes should have a meaningfull name as well.
