First analysis shows:

Can be reproduced by loading more than one image (in our case three), selecting all of them at the same time for image statistics and the closing the application.

The reason seems to be, that in case of illegal selection the observer for the selected image was not deleted, but the selected image itself was.

This resulted in a remaining observer.

Added remove observer for illegal selection

Previously when an illegal node selection was processed the selected image was set to NULL, but the corresponding observer was not removed.

Added a new function, which removes all observers and sets the members to NULL.
