Shapefile support not working

[http://wiki.navit-project.org/index.php/user:petermckinley]

Navit won't launch / crashes when configured to use Shapefiles. Result is exactly the same with Shapefiles from 2 different makers, comprising identical 5 file types, (.shp .dbf .cpg .prj .shx) including ​http://download.geofabrik.de/

<mapset enabled="yes">

<map type="shapefile" enabled="yes" data="/path/to/myshapefile.shp"/>

Running Navit from Terminal:

"

If I run Navit as root:
