[GRASS-dev] problem using GRASS Python interface from QGIS in windows

[Luca Delucchi]

Hi everybody,

for a project I'm using grass python interface from QGIS. Everything
is working on Linux (I tested different OS) but on windows I get this
error

Traceback (most recent call last):

WindowsError: [Error 6] Handle non valido

I don't know if it is a problem of GRASS, or QGIS or subprocess, can
someone help me?
