The application could be crashed by 1) Create dive site 2) Edit dive site 3) Undo until dive site is removed 4) Continue editing now non-existing dive site Therefore, hook into the dive-site-deleted signal and if the currently edited dive site is deleted, close the widget. When closing the widget, make sure that the potentially dangling pointer is reset to zero so that there is no other potential use-after-free bug.
