hmm, this is a bug in the build procedure, we will look into it...

Yup, this is a known problem that we fixed in CVS.

That seems reasonable. The last error you get is because of the lack of
EOS detection, you can
safely ignore it. This problem is fixed in CVS...

What bothers me is that you claim that the MPEG file is 1 minute and it
only plays for 9 seconds.
How did you verify that it is 1 minute playtime? It looks from the log
that the MPEG just played 
thoughout the end in gstmediaplay.

This is normal too and can safely be ignored :-)

Try this:

1. create a thread
2. click on the thread and select a disksrc from the list, set the
location to an mp3 
    audio file using the property dialog
3. add mp3parse and mpg123 t
4. add an audiosink element
5. click-and-drag on the green pads to connect the green disksrc source
pad (to the right) to
    the green sink pad in mp3parse. In a similar way, connect the src
pad of mp3parse to mpg123's sink
    and finally connect mpg123 src to audiosink sink pad.
6. on the thread object press the 3rd button on the lower left side
(with the black P in it)
7 you should hear your mp3 now.

Note that the editor is in a bad shape, both the GUI and the
functionalties it provides.

Nope, it's just that most of the end user apps are in a pretty bad
shape, especially the editor. We
are currently working on improving the core libraries first and we will
then move on to a 
complete rewrite of the player and the editor components.
