When using the geographic admin on the simple world application, the following error is raised when using Apache 2.2.9 on Ubuntu 8.10 with both mod_python (3.3.1) and mod_wsgi (2.3):

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.
