Hi Philippe, I'm pretty sure I helped you work through this problem on IRC after you sent this email. Can you send an email back with how things turned out?
For the benefit of others the problem was basically that the natural earth data often represents data stored in wgs 84 that is invalid for re-projecting to google mercator. Thus, the data needs to be clipped, and I often do this with gdal 1.7's new -clipsrc functionality.
