Hum I didn't try with MapServer, but looking at the GDAL request it does in the logs, I tried something close with gdal_translate: gdal_translate /vsicurl/http://mw1.google.com/mw-earth-vectordb/kml-samples/mv-doqq.kml out2.tif -outsize 312 300 and the good or bad news is that fails on both Ubuntu and Windows (well at least on wine/Linux) with a similar error to yours: VSICURL: Start download for http://mw1.google.com/mw-earth-vectordb/kml-samples/mv-070501/422.kml VSICURL: Stop download for http://mw1.google.com/mw-earth-vectordb/kml-samples/mv-070501/422.kml VSICURL: Start download for http://mw1.google.com/mw-earth-vectordb/kml-samples/mv-070501/422.JPEG VSICURL: Stop download for http://mw1.google.com/mw-earth-vectordb/kml-samples/mv-070501/422.JPEG GDAL: GDALOpen(/vsimem/kmlsuperoverlay/6_0x1d0f878, this=0x1d12bd0) succeeds as JPEG.

Mind opening a GDAL ticket about that ?
