see  https://trac.osgeo.org/grass/ticket/1025

an error occurred and the error detection logic failed so you don't
see the useful error message explaining what went wrong.

the downloaded "tiff" image probably contains some text file.
you'll have to remove it otherwise it will think the tile is already
downloaded.


as it generally works for me, I'd need to know the output of:

  cd $GISBASE/wms_cache/
  file -b really_a_xml.tif

in order to improve it.

what operating system + version do you use?



often the "-g" flag helps when working with older WMS servers.



good luck,
Hamish
