I managed to trap one problematic case but there is something weird 
going on. The feature comes originally from Oracle and it is for sure 
a polygon there (GTYPE=2003). I have converted it into shapefile with 
GDAL 1.6 and OCI plugin from OSGeo4W because for some reason I have 
not managed to connect our Oracle with more recent versions.

Now GDAL 1.6 that I used for converting polygon from Oracle into
shapefile tells that geometry is a polygon, while GDAL 1.9 claims 
that it is a multipolygon.

Ogr2ogr of GDAL 1.9 with this shapefile created by GDAL 1.6 leads 
to an error:

ogr2ogr -f SQLite -dsco spatialite=yes -dsco init_with_epsg=yes
-a_srs epsg:2393  multi.sqlite multi.shp

ERROR 1: sqlite3_step() failed:
  multi.GEOMETRY violates Geometry constraint 
[geom-type or SRID not allowed] (19)
ERROR 1: ROLLBACK transaction failed: cannot rollback - no 
transaction is active

ERROR 1: Terminating translation prematurely after failed
translation of layer multi (use -skipfailures to skip errors)

The error is the same even if I use -nlt multipolygon.

If I convert the GDAL 1.6 shapefile into a new shapefile with GDAL 1.9 the
geometry is reported to be of type POLYGON and conversion into spatialite is
successful. I cannot say if the problem is in GDAL 1.6 or in the Oracle OCI
driver or what but anyway I believe that the shapefile is somehow corrupted or
at least GDAL 1.9 thinks so.

The one-feature shapefile (multi?)polygon shapefile created by 
GDAL 1.6+OCI is here
