Yup, this is a clear bug. I just submitted completely rewritten mp3 header
parsing code to the ecasound CVS. I throwed the old layer.cpp away
altogether (well, physically it's still there but it's not used). The new
code is based on the mpg123 plugin that comes with XMMS v1.2.5pre1.

Additionally, by raising debug level to 'user objects' (or -d:255 to get
everything), you get the following output:

(audioio-mp3) Total file size (bytes): 3676706.00
(audioio-mp3) Bitrate (bits/s): 128000.00
(audioio-mp3) Sampling frequncy (Hz): 44100.00
(audioio-mp3) Total length (frames): 8796
(audioio-mp3) Total length (seconds): 230
(audioio-mp3) Pcm per mp3 frames: 1152

... if something still goes wrong, send me the above info.
