no error message when using old GDAL and trying to get GEOJSON

Description

I was trying to get GEOJSON from a GEOSGeometry object with an old version of GDAL (1.3.2) I did the following:

from django.contrib.gis.geos import *

poly = GEOSGeometry('POLYGON (( 10 10, 10 20, 20 20, 20 15, 10 10))')

poly.json

and got nothing back. doing the gdal.HAS_GDAL test returned True

looking at the code it seems it should have returned an error that my GDAL version was too old, but I got nothing.

(In [10131]) Refactored the GEOS interface. Improvements include:

* Geometries now allow list-like manipulation, e.g., can add, insert, delete vertexes (or other geometries in collections) like Python lists. Thanks, Aryeh Leib Taurog. * Added support for GEOS prepared geometries via prepared property. Prepared geometries significantly speed up certain operations. * Added support for GEOS cascaded union as MultiPolygon.cascaded_union property. * Added support for GEOS line merge as merged property on LineString, and MultiLineString geometries. Thanks, Paul Smith. * No longer use the deprecated C API for serialization to/from WKB and WKT. Now use the GEOS I/O classes, which are now exposed as WKTReader, WKTWriter, WKBReader, and WKBWriter (which supports 3D and SRID inclusion) * Moved each type of geometry to their own module, eliminating the cluttered geometries.py. * Internally, all C API methods are explicitly called from a module rather than a star import.
