Comment:
Marking this as invalid because it can't be fixed without scanning every
feature in the shapefile. This is because the
[http://www.gdal.org/ogr/drv_shapefile.html OGR driver] can't
differentiate between the formats:
"Note that when reading a Shapefile of type SHPT_ARC, the corresponding
layer will be reported as of type wkbLineString, but depending on the
number of parts of each geometry, the actual type of the geometry for each
feature can be either OGRLineString or OGRMultiLineString. The same
applies for SHPT_POLYGON shapefiles, reported as layers of type
wkbPolygon, but depending on the number of parts of each geometry, the
actual type can be either OGRPolygon or OGRMultiPolygon."
This is because the
[http://www.esri.com/library/whitepapers/pdfs/shapefile.pdf shapefile
specification] itself doesn't differentiate between `Polygon` and
`MultiPolygon`.
