If it's just audio you're trying to decode (and not, say a movie), you
could just try with a simpler pipeline, f.i.
filesrc location="name-of-your-mp3" ! mad ! audioconvert ! audioresample
! osssink
(note that osssink most likely would need to be substituted with
whatever sink you'll be using...) In this simpler way you'll see if your
problem stems from a mad library situation or from your previous use of
decodebin2. And btw in principle you don't need to load libmad yourself,
it'd be done by the gstreamer plugin library.
What you could also try is running "ldd -v libgstXXX.so" which will walk
the shared library tree of dependencies for a plugin named XXX, normally
under /usr/lib/gstreamer-0.10, you could start with libgstdecodebin2.so
or libgstmad.so; perhaps the problem is a dependency of a dependency...
