Hi Nyall,
IIR the rubber band adds two points because the second one will be used
to track the mouse moves.
Basically addPoint is synonym of add point to line. It shall not be used
if you want to have single points.
Cheers,
Denis

Hi all,
I'm struggling to understand the rationale behind some logic in
QgsRubberBand::addPoint. At line 163
(https://github.com/qgis/QGIS/blob/master/src/gui/qgsrubberband.cpp#L163),
if a new geometry index is required then it is added and the specified
point added to this new geometry index.
That's fair enough, but the very next code block will then re-add that
same point to the new index. The result is that the first point will
always be added TWICE to the rubber band.
Is this deliberate? Or a bug in the code?
