Description
Hi, found this bug when trying to create voronoi polygons. The algorithm failed with this error:
2016-11-08T11:03:51 2 Uncaught error while executing algorithm
Traceback (most recent call last):
File "/usr/share/qgis/python/plugins/processing/core/GeoAlgorithm.py", line 203, in execute
self.processAlgorithm(progress)
File "/usr/share/qgis/python/plugins/processing/algs/qgis/VoronoiPolygons.py", line 110, in processAlgorithm
total = 100.0 / len(c.polygons)
ZeroDivisionError: float division by zero
Cheers

Hi, I've recived today the same error in Qgis 3, with postgres layer and with a shapefile. Must be reopened?

The division by len(c.polygons) is protected by a test for zero in the current master.
