Script for playing a video and then switching the audio or video track

See the attached script. If I run it against this matroska file, switching
playbin's "current-audio" causes it to stop playing and lock up:

    # Download this file to test.mkv:
    # https://www.dropbox.com/s/aggvr6ch12oqy76/test.mkv
    gst-git ./switch-track.py file:///$PWD/test.mkv audio

Switching the video track works fine though:

    gst-git ./switch-track.py file:///$PWD/test.mkv video

Also it works in this ogg file:

    # Download to test.ogv
    # https://www.dropbox.com/s/69iigecsec0gcp3/test.ogv
    gst-git ./switch-track.py file:///$PWD/test.ogv audio
    gst-git ./switch-track.py file:///$PWD/test.ogv video
