Hi,
Thank you for this short discussion, now I think there is light at the
end of the tunnel.
I tried solve my problem with MapServer 6.4.1 and GDAL 1.9, but that
gdal version has write-only support for kml superoverlays.
First step is to change GDAL version in my project...

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:

Not sure why you get different results.
Mind opening a GDAL ticket about that ? I'm debugging something else
tricky right now ;-)
