    Don't let the GtkCellRendererToggle get activated by clicking on a tree row
    
    GtkTreeView activates a row when it's clicked or double-clicked, which ends
    up toggling the GtkCellRendererToggle in the linking dialogue even if it's
    insensitive, allowing the start Individual to be removed from the link, and
    causing chaos. See bgo#567481. Closes: bgo#628011
