 dev/2018-November/090480.html) I now understand that the mkdir part in
 lib/python/script/core.py fails.

 I disagree, the mapset should have been created by g.proj:

 The patch does not create a valid mapset, it creates only an empty
 directory: the files DEFAULT_WIND, PROJ_EPSG, PROJ_INFO, PROJ_UNITS, WIND
 are missing.

 You need to find out why g.proj called by create_location() has not
 created the location with mapset PERMANENT
 (/actinia_core/grassdb/latlongtest/PERMANENT)
