Hi!

I've debugged a bit with the aRts mp3 playobject and the mpeglibartsplay
stresstest, and managed to reproduce both problems that this causes without
aRts. I simply turned the mpeglib splay example in a stresstest, and it
causes

 - the memory leak
 - the segfault

in the same way. Maybe this simplifies debugging. I've attached a patch
which you can apply to kdemultimedia/mpeglib/example/splay/Makefile.am,
and the additional stresstest program called testsplay.

   Cu... Stefan
