Hi,
thanks for your answer. Seems memory layer is the only way to go.
Best regards

Hi Adam
I think the idiomatic way to do this would be to rather make (convert rubber
bands to) a memory layer with some features that you need displayed for
printing and then remove it again after the print is done (aka a redlining
layer).

Hi Radim,
It seems it is your point that has been deleted, not the rubber band.
Doing print point before addPoint crashes.

Good, thanks and sorry for false pointing to rubber band.
However, do you have any idea

Thanks Denis,
However, do you have any idea where the point may be deleted? The
points are acquired from QgsGeometry.asPolyline() which returns
QVectorQgsPoint, i.e. list of values. The points are then add to
another list: result.extend( pnts[1:-1] ). Is it wrong? The points get
deleted with

thanks to Salvatore's help on irc, i got over this issue.
apparently the 'isPolygon' method was deprected..
here is the snippet that worked..
mCanvas = iface.mapCanvas()
rb = QgsRubberBand(mCanvas,QGis.Polygon)
rb.addPoint(QgsPoint(300,300))
rb.addPoint(QgsPoint(400,400))
