QGIS » QGIS Application

With some complex (and maybe a bit uncorrect geometries) like the one I attached here below, if the geometries validator is set on QGIS, when I select it with the nodetool, Qgis crashes.
The fact is that it happen with all the realeses of the 2.14, both for windows and mac, while the same geometry had no problem at all with the releases of the version 2.8.
Setting the validator on GEOS or Off (obviously) the are no problems.

This is the report of the crash:
