Geometry generator symbol layer crashes QGIS for invalid SpatiaLite geoms

[qgib]

Author Name: Anita Graser (@anitagraser)
Original Redmine Issue: 14933
Affected QGIS version: 2.14.3
Redmine category:symbology

---

QGIS crashes if the invalid polygon in the attached Spatialite db is rendered with a geometry generator with centroid function:

!geomgen.png!

There is no crash if the same feature is saved to Shapefile for example.

Tested with 2.14.2 on Ubuntu and 2.14.3 on Windows.
