I've had good luck with this snippet, dropped in mu-plugins or 
functions.php, for preventing these "oops" moments.

    add_action( 'wp_trash_post', 'prevent_oops' );
    add_action( 'before_delete_post', 'prevent_oops' );

    function prevent_oops( $postid ) {

         if( $postid == get_option( 'page_on_front' ) || $postid ==
    get_option( 'page_for_posts' ) ) {
             wp_die( 'You are trying to delete a very important page.' );
             exit;
         }

    }

Not as slick as it could be, but gets the job done, and could be 
augmented to check for a post meta flag that would allow other pages to 
be 'protected' from deletion.

Been there done that, not nice at all.

Hope that helps.
