Description

On r15297 I get incomplete number of polygons when intersecting with the Geoprocessing tool 'Intersect' from fTools.

I attach two shapefiles for testing purposes.

In the command line I get this error:
---------------------
ERROR 1: Attempt to write non-polygon (MULTILINESTRING) geometry to POLYGON type shapefile.

It occurs because the intersection operation generates different geometries types!
In your case, it generates a MultiLineString geometry and try to write in a Polygon geometry.
I sent a pull request that should fix it!
