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&lt;T&gt;::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.
