FS#141 - SIGABRT drawing circle crashes

  1. new drawing
  2. tools → circle
  3. click center → crash

source code segment:

void RGraphicsSceneQt::exportArcSegment(const RArc& arc) {
    RPainterPath& path = draftMode ? currentPainterPathDraft : currentPainterPath;
 
    // try QPainterPath arcTo method first but this can be very
    // inaccurate (+/- 0.01 difference from start- / end point):
    RPainterPath p;
    RBox box(arc.center - RVector(arc.radius, arc.radius), arc.center
            + RVector(arc.radius, arc.radius));
    p.moveTo(arc.getStartPoint());
    p.arcTo(box.toQRectF(), 360 - RMath::rad2deg(
            arc.startAngle), -RMath::rad2deg(arc.getSweep()));
=>  QPainterPath::Element e1 = p.elementAt(1);
    double errorStart = RVector(e1.x, e1.y).getDistanceTo(arc.getStartPoint());
    QPointF ep = p.pointAtPercent(1.0);
    double errorEnd = RVector(ep.x(), ep.y()).getDistanceTo(arc.getEndPoint());
 
    if (errorStart<1.0e-5 && errorEnd<1.0e-5) {
        // TODO: check if this is ever reached:
        path.addPath(p);
        return;
    }
