wcs issues on getting data

[Nuno GIL]

Dear listers,
I've installed mapserver in order to use its wcs
capabilities.
The GetCapabilities request works fine, the problem is
when I try to use the GetCoverage request. Actually I
don't receive any error message, but the received file
is empty.
I'm querying the server with this request:
http://iceds.ge.ucl.ac.uk/cgi-bin/wcs?REQUEST=GetCoverage&COVERAGE=l5&SERVICE=WCS&map=/ge/data/iceds/alpha/umms/wcs_land3.map&BBOX=48.5,-21.5,48.7,-21.3&FORMAT=GEOTIFF_RGB&CRS=EPSG:4326&RESX=0.00027778&RESY=0.00027778

Just to try and sort out the problem, I reduced the
data being served to only a simple image with one
channel (no tiles), no  results as well...

Used the gdalinfo utility to check some parameters of
the image:

Driver: GTiff/GeoTIFF
Size is 1800, 1800
Coordinate System is `'
Origin = (48.500000,-21.000000)
Pixel Size = (0.00027778,-0.00027778)

  TIFFTAG_SOFTWARE=Arc/Info

  TIFFTAG_YRESOLUTION=3599.999
  TIFFTAG_RESOLUTIONUNIT=1 (unitless)
Corner Coordinates:
Upper Left  (  48.5000000, -21.0000000)
Lower Left  (  48.5000000, -21.5000000)
Upper Right (  49.0000000, -21.0000000)
Lower Right (  49.0000000, -21.5000000)
Center      (  48.7500000, -21.2500000)
Band 1 Block=256x256 Type=Byte, ColorInterp=Gray

and the map file looks like this:

Does anyone understands what is going wrong? Any help
would be much appreciated.
