Okay, here is a related scenario. Run check reports that file foo.jpg is not referenced. Double click (not single click) on said error message such that foo.jpg image is shown in the tabbed document editing pane, delete foo.jpg via Files Browser (i.e. right click on filename and delete). Double click (not single click) again on said error message. Exception will occur.
