The file works perfectly well on my machine when using the spider.
Actually I fixed a glib warning first, but that wasn't your problem.

The --gst-mask output indicates that it is a typefinding problem.
Whenever there is an eror in typefinding, the
spider tries the for the
whole song to find the right type. So the whole file is processed and
gst-launch exits cleanly but you get no output.

The things I could think of right now:
- mp3 typefinding for some reason isn't installed. Or it's installed in an
old version. (gst-inspect mp3types)
- It's a problem with big endian support in mp3 typefinding.
You - or someone else with endian knowledge - might
want to look at plugins/gst/mpegaudioparse/gstmp3types.c and look for
endian bugs there. Especially in the if clause with the id3 tag.
