Description

Tested on Linux and Windows (raster layer attached) on 2.18.13

2017-09-19T19:29:30    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/ZonalStatistics.py", line 232, in processAlgorithm
                numpy.isnan(srcArray))))
            ValueError: setting an array element with a sequence.

This is a regression as the tools worked fine in previous releases.

Note: if sample polygon(s) are smaller than a pixel size then the tool runs but the output is empty, see also: #17159

On master seems ok, but still #17159
