However, this does not happen on Ubuntu 8.04 (Apache 2.2.8 + same version
of `mod_python`). The attached patch fixes the exception. Basically,
instead of doing the transform ops on the GEOS geometry, I get an OGR
geometry first and do the transform. Other than reducing transformation
complexity (e.g., I'm not instantiating OGR geom within
`GEOSGeometry.transform`), I don't know why this works -- which is why I
have this ticket. See also [http://tinyurl.com/6goeal this django-users
