Hi Jeff,
Thanks for taking the time to investigate that !
That is what I feared, but it is not such a big deal as we can still use
csv export and write our own KML creation function.
It would have been much worse if the issue had been about Shapefile export.
I will create the ticket as soon as possible.
Thanks and hello from Quebec !
Bruno
