[Qgis-developer] Possible issue with QgsRubberBand

[Nyall Dawson]

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?
