The gtop program (and the hpd device driver which I mined for another device) uses a routine called 'devarc' to compute a center and radius for an arc given three points. This routine core-dumps (division by 0) if the points are collinear (which happens in thin slices generated by "pie" sometimes). This should be fixed to draw a line between the points, of course. Mike
