r.in.wms doesn't always process WMS server responses (errors)
Current r.in.wms implementation is simply downloading data and not performing any kind of response parsing. If some WMS parameters are wrong, r.in.wms still will download and process error messages as if they where normal server responses. There's no use for few thousands of XML files with content i.e. "Output format not supported", also any processing of such "GeoTIFFs" will fail.
