    shell-search-provider: warn against NULL strings before normalizing
    
    Since g_mount_get_name() and nautilus_bookmark_get_name() can possibly
    return NULL, warn against it before normalizing the string and trying to
    compare it with the search terms. This fixes a crasher in the shell
    search provider.
