Description
I can make a geometry like this:
pol = [ QgsPoint(0,0),QgsPoint(0,1),QgsPoint(1,1)] QgsGeometry.fromPolygon([pol])
<qgis.core.QgsGeometry object at 0x998aeac>
but if I do:
pol = [] QgsGeometry.fromPolygon([pol])
- crash:
Fatal: ASSERT failure in QVector<T>::operator[]: "index out of range", file /usr/include/qt4/QtCore/qvector.h, line 320
- this happened when a selection tool I wrote was trying to create a geometry from a list of coordinates that it hadn't filled yet. Carson Farmer had the same problem.
