I believe the python library was formally introduced, and definitely refined,
after the 6.4.2 release. So the one that came with your copy of QGIS is too
old. Please try a recent nightly build of 6.4.3svn,

  http://grass.osgeo.org/download/software/ms-windows/

(and let us know how it goes, python scripts on Windows suffer from
filename extension confusion when multiple copies of Python are
installed by different programs, each of which wish to be associated
with ".py", and so any feedback that helps us navigate through that
maze is quite valuable, especially from anyone who knows the Python
on Windows quirks well)
