Martin,

If your script only does CreateFeature() to build a shapefile from scratch, 
then it is really annoying that ArcGIS protests, and we should fix that. But no 
idea what would cause it.

If your script does edits with SetFeature() or DeleteFeature(), then the 
extent advertized in the shapefile might be larger than the actual extent of 
the shapes in it. I'm not sure how ArcGIS could detect that without iterating 
over the whole shapefile to make the comparison. If you're in that case, you 
can try issuing "RECOMPUTE EXTENT ON layername" with ExecuteSQL() / ogrinfo -
sql. See "Spatial extent" paragraph of http://gdal.org/drv_shapefile.html
