Using a Spanish locale, the following error appears when trying to
register maps in a STRDS using the python interface:

{{{

}}}

Changing the system settings to English fix the issue.

Comment (by lrntct):

Below is a minimum working example. Try to run it with a Spanish locale,
it will fail. In English, it will run OK.

{{{
import grass.temporal as tgis
import grass.script as gscript
import grass.pygrass.utils as gutils

def create_map_list():
     """Create a list with random raster maps"""
     map_list =
     for i in range(5):
         map_name = 'map_test{}'.format(i)
         map_id = '{}@{}'.format(map_name, gutils.getenv('MAPSET'))
         # create random raster map
         gscript.run_command('r.random.surface', output=map_name,
overwrite=OVR)
         # populate list
         map_list.append((map_id, i))
     return map_list

def register_maps_in_stds(stds_id, map_list):
     """Create a STDS, create one RasterDataset for each map and
     register them in the temporal database
     """
     # create stds
     stds = tgis.open_new_stds(stds_id, 'strds', 'relative',
                               "test", "", "mean", overwrite=OVR)

     # populate MapDataset objects list
     map_dts_lst =
     for map_id, map_time in map_list:
         # create MapDataset
         map_dts = tgis.RasterDataset(map_id)
         # load spatial data from map
         map_dts.load()
         # set time
         map_dts.set_relative_time(map_time, None, 'seconds')
         # populate the list
         map_dts_lst.append(map_dts)
     # Register the maps
     tgis.register.register_map_object_list('raster', map_dts_lst, stds,

tgis.init()
register_maps_in_stds('strds_test', create_map_list())

Comment (by neteler):

Attached a patch to remove undesired gettext macros from debug messages -
a will guess: does it help?
