A simple workaround to the problem consists in commenting the
method "CircleImp::draw" in both objects/circle_imp.cc and
objects/circle_imp.h.
In this way kig falls back to the generic method for drawing conics,

An identical problem is present when drawing circular arcs! Since the
correction is minimal and perfectly similar to what was done for circular arcs
I took the liberty of pushing it into
origin/master.

Anyway, there are still problems when drawing arcs and circles; apparently of a
different
nature: it becomes apparent when the radius of circle/arc is much larger then
the size
for the displayed canvas. I will

A standalone minimal C++ program using Qt5 and drawEllipse shows that the
precision
loss with circles having large radius is actually a Qt problem!
I will try to file a qt bug report about this problem.
