    thumbnailer: fix double close()
    
    A file descriptor used to communicate with the video thumbnailer process is
    closed twice. In case another thread allocates the same descriptor number in
    the meantime, the second close() actually closes a descriptor not owned by the
    thread. This causes crashes in most cases or unexpected behaviour.
