PFTRAV_IS_PATH problem with pfSegsIsectNode (again)

Hi,

I have been trying to obtain the traversal path to an intersected node by
setting PFTRAV_IS_PATH in the segSet mode passed to pfSegsIsectNode.

I have no problem obtaining correct intersections with geometry when the
mode is set to other combinations (PFTRAV_IS_PRIM|PFTRAV_IS_NORM).
However, when PFTRAV_IS_PATH is ORed in (and absolutely no other change
made) not only is the path not returned but the entire intersection request
fails.

If it makes a difference, the geometry with which the segment should be
intersecting is under a pfDCS which is under a pfSwitch which is attached
directly to the pfScene.

Does anyone have any ideas ?

I know that exactly the same question was asked a few months ago by
someone else but there did not seem to be any (public) response.
