GStreamer log message ( turn on with export GST_DEBUG=7 ).

I tried to look into this issue. Despite the .wav selected for the effect
doesn't work while the slideshow is running, you can hear the sound when you
click the play button in the custom effect dialog.

export GST_DEBUG=7 and logging the messages of those two situations, the
slideshow has following error messages:

( note that gst_element_message_full_with_details said it can't demultiplex the
stream, in Chinese. The message doesn't matter. )

I'm still trying to figure out what's going on there.
