Before creating a qix file with shptree I get features using the following ogrinfo command:
ogrinfo D:\bart\dtb\dtb_subset\dtb2000_sym.shp dtb2000_sym -spat 60000 400000 90000 410000
When I create the qix file with shptree, and rerun the exact same command, I get no features returned anymore:
shptree D:\bart\dtb\dtb_subset\dtb2000_sym.shp
D:\bart\FWTools1.3.6>ogrinfo D:\bart\dtb\dtb_subset\dtb2000_sym.shp dtb2000_sym

I believe the same problem is present in OGR and Mapserver.
I tested with latest FWTools 1.3.6 on Windows.
