pfdPrintSceneGraphStats() uses the INFO notification level. If you see
only your own message printed, then I assume the scene pointer is NULL
unless your scene graph doesn't contain any recognized primitives: TRIS,
LINES and POINTS.
Since the source for pfdPrintSceneGraphStats() is available in
/usr/share/Performer/src/lib/libpfdu/pfdLoadFile.c, I suggest you take a
look at the function, recompile with -g and step through to verify what's
going on.
Gook luck.
