871 | * will for urls like "about:about", "about:config" etc), |

873 | * history_update will either explode or overwrite the node |

875 | * |
876 | * We call it after, rather than before urldb_add_url because |
877 | * history_add calls bitmap render, which tries to register |
878 | * the thumbnail with urldb. That thumbnail registration |
879 | * fails if the url doesn't exist in urldb already, and only |
880 | * urldb-registered thumbnails get freed. So if we called |
881 | * history_add before urldb_add_url we would leak thumbnails |
882 | * for all newly visited URLs. With the history_add call |
883 | * after, we only leak the thumbnails when urldb does not add |
884 | * the URL. |
885 | * |
886 | * Also, since browser_window_history_add can create a |
887 | * thumbnail (content_redraw), we need to do it after |
