Naturally it would be great to be able to reproduce this in some kind
of minimal sample, or at least find out if the same operation also fails
on *nix system.

Anyways, to rule out if this is a problem with the used compiler, here is
a link to GEOS DLLs built with Visual C++ 7.1 (the same one used to build
Python 2.5):

Just copy the files into your Python25\DLLs directory, and let us know
if it works any differently.

Thanks,
