 Summary of the bug:

 In ffmpeg-0.8.12 ffprobe correctly recognizes teletext in transport
 streams:
 Stream #0.2[0x13f0](deu): Subtitle: [6][0][0][0] / 0x0006

 In later versions (including the current GIT) the output for the same
 recorded transport stream is
 Stream #0:2[0x13f0](deu): Audio: mp1 ([6][0][0][0] / 0x0006), 0 channels,
 s16p

 I can easily provide a sample on request.
