event conflict with official/group_persistence. Moving to contrib forces toggle_group_view to load before group_persistence and thus get events that both need, first. If the order is reversed then toggle_group_view can bog down in a loop making darktable unresponsive. Fixed bad call in destroy and added check for selection-changed to make sure there are images before trying to set sensitivity.
