[GRASS-dev] v.what.rast in a python script causes "grass.exceptions.CalledModuleError"

[Helmut Kudrnovsky]

hi,

I've a addon script:

http://trac.osgeo.org/grass/browser/grass-addons/grass7/vector/v.habitat.dem

which calls v.what.rast

http://trac.osgeo.org/grass/browser/grass-addons/grass7/vector/v.habitat.dem/v.habitat.dem.py#L297

this gives following error:

--------------
Upload DEM zonal statistics to the attribute table ...

PRECISION', 'e_dem_range DOUBLE PRECISION', 'e_dem_average DOUBLE
PRECISION', 'e_dem_median DOUBLE PRECISION']'

Process ended with non-zero return code 1. See errors in the

-----------

the columns in the attribute table are correctly be filled by the stats
data.

any idea the error?
