Hi Soeren,

We disabled the removal of the temporary file (map_0) that GDAL tries
to load, and checked what it contained in three different cases:

1) direct call of a local file (in cgi-bin folder):
http://131.175.143.108/cgi-bin/zoo_loader.cgi?Service=WPS&Request=Execute&Version=1.0.0&Identifier=r_univar&DataInputs=map=DTM_108.tif;grass_band_number=1

The file map_0 contains only the name of the file as text (without
quotes): "DTM_108.tif"

2) URL encoded WCS request (WCS server by MapServer):
http://131.175.143.108/cgi-bin/zoo_loader.cgi?Service=WPS&Request=Execute&Version=1.0.0&Identifier=r_univar&DataInputs=map=Reference@xlink:href=http%3A%2F%2Fows.como.polimi.it%2Fcgi-bin%2Fdtmserver%3FSERVICE%3DWCS%26VERSION%3D1.1.0%26REQUEST%3DGetCoverage%26coverage%3DB4DTM%26CRS%3DEPSG%3A3003%26BBOX%3D1500000.000%2C5070000.000%2C1540000.000%2C5095000.000%26WIDTH%3D800%26HEIGHT%3D500%26FORMAT%3DGTiff;grass_band_number=1

The error is the same, and the file map_0 contains this text:

--wcs
Content-Type: text/xml
Content-ID: wcs.xml

<?xml version="1.0" encoding="UTF-8"?>
<Coverages
     xmlns="http://www.opengis.net/wcs/1.1"

  </Coverage>
</Coverages>
--wcs
Content-Type: image/tiff
Content-Description: coverage data
Content-Transfer-Encoding: binary

II*

3) URL encoded with a direct HTTP link to the file:
http://131.175.143.108/cgi-bin/zoo_loader.cgi?Service=WPS&Request=Execute&Version=1.0.0&Identifier=r_univar&DataInputs=map=Reference@xlink:href=http%3A%2F%2F131.175.143.108%2Ftmp%2Fb4d4.tif;grass_band_number=1

The error is the same, and the file map_0 contains this text (without
quotes): "MM"

Best regards
