Description

Add an observer to an image who listens to the itk delete event. while removing the image form the datamanager there is neither an itk event fired nor the destructor is called. during searching for the reason we also found out that there is no event fired for a datanode.

We found out that the segmentation view holds a smartpointer to the corresponding data node and thus the node isn't deleted when it was removed from the datamanager.

The reference is most likely held in the mitkComputeContourSetNormalsFilter.

Tobi can you check that?

I think this bug is fixed with T17993. There a test for the delete event is performed and it passes
