The media is broken. Specifically, the text media playlist (e.g. 09.m3u8) contain discontinuities where-as the variant media playlists (e.g. 01.m3u8) do not. More worryingly, if you look at the snippet of 09.m3u8 below, it's listing the exact same segment twice around the discontinuity, with two different durations. A segment can only have one duration, and should only be listed once.

If you disable the text track (it's selected by default as this is what the master playlist requests) then playback proceeds successfully.
