GStreamer seems to leak memory when the registry is read in, as the 
following program shows: 
 
 
int 
main (int argc, char **argv) 
{ 
   gst_init(&argc, &argv); 
   return 0; 
} 
 
 
gst_structure_from_string()/_gst_caps_from_string_inplace() seem to be 
the major culprits. 
 
 
Here is the valgrind output:
