    use gst_bus_timed_pop instead of gst_bus_poll in metadata code
    
    Described as 'pure evil' in the GStreamer API doc, gst_bus_poll runs the
    mainloop to process messages, which allows the metadata helper's
    inactivity timeout to be called during metadata save operations, killing
    metadata save operations that took longer than the timeout.
