 Problem is manifested using a python script. Script and data provided as
 attachment.

 !!! The script must be tweaked slightly in the beginning to match the
 grass install path. A proper GRASS DB must be provided there with a BG_DEM
 location and a PERMANENT mapset projected in EPSG:32635 (UTM Z35N)
