Now that the goldenpoint got merged in master, we should also push this bug patch (in master). I can take care of that.
perhaps a bug should also be merged into other branches of kig?

I think we should wait for David Narvaez to decide what to do

As I said, this is not a probem specific of the Golden Ratio. You should have a look at the bug report https://bugs.kde.org/show_bug.cgi?id=394676
This is a consequence of a somewhat obscure information that can (should) be associated to a construction.
I know this very well since I am responsible for it.

I just filed a bug report for the problem mentioned above: https://bugs.kde.org/show_bug.cgi?id=394676
in that report there is no mention of the new GoldenRatio property; it would raise the number of properties
of a segment from 5 to 6, the method mentioned in the bug report should return "true" for the GoldenRatio
property, since the constructed point is contained in the segment.
About the crash above: the problem resides in AbstractLineImp::isPropertyDefinedOnOrThroughThisImp...
However it involves more than the new Golden Point. Perhaps the right action should be to file a bug
It seems that the implementation of this property is wrong with respect to the hierarchy of objects
I get a crash with a construction involving the new 'golden ratio' point:
- construct a segment s = AB
- construct the golden point G from the segment
- circle of center C (somewhere) through G
- position C such that the circle has two distinct intersections with the segment, one is G
- contruct the intersections between the segment and the circle

I would not object in accepting this revision
Concerning the external point... I would *not* add a construction for it... I am afraid that such construction would be somewhat confusing.
As you see... most (if not all) of the figures representing the golden section show the larger segment on the left. And when you say
"short to long equals long to whole", this is simply the result of a phrase where the subject is actually the "long", something like
"the long is 'in between' the whole and the rest".
Moreover you could as well say
"whole to long equals long to short" (and I would prefer this latter phrasing as more corresponding to the definition:
I have one remark. Since the result is different depending on how we orient the segment (say) AB we have to decide if the construction
gives the point on the segment nearest to A or the one nearest to B. The proposed solution:
