Hi!
It seems that I have run into the same problem that was reported earlier by Philip. I have a freshly installed python mapnik and the first attempt at running generate_image.py causes a Segmentation fault in mapnik.render(). When I change the script to use render_to_file(), there is no error and a valid image is created that looks just like it should. I would need to solve this problem as I'm trying to build up a major rendering chain on the server.

At the core is a C++ shared library providing algorithms/patterns for spatial data access and visualization. . Essentially a collection of geographic objects (map, layer, datasource, feature, geometry), the library doesn't rely on "windowing systems" and is intended to work in multi-threaded environments . High-level Python bindings (boost.python) facilitate rapid application development, targeting zope3, django, etc. . This package contains the Python bindings.
