Hi, i'm using Qwt 5.2.2. I have recieved segfault on method QwtPlotCurve::drawDots() cause:
QwtPolygon polyline; (line 882)
doFill == false AND d_data->canvasRect.isEmpty() == true (line 888)
so, in (line 893)
polyline.setPoint(0, ...); (index out of range)
and then s*it happens.

Is it bug or if not how it could be possible?
Sorry, my English is horrible, tried to minimize sentences.
