Comment 16 for bug 836707

the warning "gtkliststore.c:797: Invalid column number 155650272 added to iter..." comes from the call to gtk_list_store_insert_with_values at midori-browser.c:693 (that's the first one in midori_bookmark_folder_button_new).

but then it's not quite clear how it comes up with such a value, given it's just:
gtk_list_store_insert_with_values (model, NULL, G_MAXINT,
        0, _("Toplevel folder"), 1, PANGO_ELLIPSIZE_END, 2, 0, -1);

my only guess is that the gtk_list_store stuff doesn't play well with G_TYPE_INT64.
