Bruno: since you get all the credit for this research, can you please
file this as a ticket at : https://github.com/MapServer/MapServer/issues
(include your mapfile and commands, nothing about mapscript). I
believe this is something to do with how inline features are handled,
for labels, in KML output. (maybe related to the message
"msINLINELayerOpen: Layer is already open!" that MapServer is yelling at
us, ha)
Thanks and hello from the east coast of Canada,
-jeff

Sorry I should have said at first that I already checked that. I have
both KML and LIBKML drivers listed.
And KML output works if I remove the LABEL entry from my mapfile...

Hi Bruno,
Next test is to test that your local GDAL was built with KML support:
ogrinfo --formats
(you should see a 'LIBKML' or 'KML' driver listed there, either one can
be used for this)
