I hope you don't think that I got that last output from amarok. I
executed the pipline you told me:
gst-launch-0.8 filesrc location=<mp3file> ! spider ! audioscale ! audioconvert ! artsdsink
So I don't see amarok do anything in this... But anyway, I'll attach the
stuff I get from the following commands.

Sure, no problem...

Ok, I attach 3 files, the first one is the debug-output of amarok (via
kdDebug()) telling some parameters used inside the GstEngine::init()
function. The next file is the output of "thread apply all bt full"
after the first break (just before the printing of
GStreamer-CRITICAL **: gst_object_check_uniqueness: assertion `name != NULL' failed).
The last one is the backtrace (again the full version) from the next
reaching of the breakpoint.

It seems that amarok calls gst_init_check in the wrong way and also
creates the pipeline not right...
