        Note: there is a ticket related to this issue here:

        Backstory: Ole Nielson pointed out an issue to me
        (Tim Sutton) where simplify ftools was dropping
        features. This test replicates that issues.

        Interestingly we could replicate the issue in PostGIS too:
         - doing straight simplify returned no feature
         - transforming to UTM49, then simplify with e.g. 200 threshold is ok
         - as above with 500 threshold drops the feature

         pgsql2shp -f /tmp/dissolve500.shp gis 'select *,
           transform(simplify(transform(geom,32649),500), 4326) as
           simplegeom from dissolve;'
