[Qgis-user] QGIS and Python Errors

[Andre Joost]

Hello,
I have installed Python 27 and Mapnik completely separate from the 
OSGeo4w path, to avoid any interference. PATH and PYTHONPATH both point 
to the standalone versions, while Qgis and Osgeo4w set their own path 
with qgis.bat and osgeo4w.bat until the end of the session.

Greetings,
André Joost
