Try the geomorpho example form the training manual.
Thanks.

Checked https://github.com/qgis/QGIS-Documentation/blob/master/source/docs/training_manual/processing/geomorpho.rst and it does not contains any links to sample data. I can use any DEM raster for it, right?

Interesting. Then it might be due to local factors (IT locale?). My command:
"/usr/share/qgis/python/plugins/processing/algs/qgis/ZonalStatistics.py", line 230, in processAlgorithm
attrs.insert(idxMin, float(masked.min()))
Results attached.
