[Gfoss] Errore durante l'esecuzione di codice Python con plugin R

[claudia.santese a cooperativaimpronte.it]

Ciao a tutti, 
credo di avere dei problemi con Python, perchè non è il primo plugin che
mi da problemi.
Qualcuno sa aiutarmi?
1° PROBLEMA]se provo ad aprire il plugin PYTHON BATCH PROCESSING --> si
blocca completamente qgis (errore windows: QGIS.EXE HA SMESSO DI
FUNZIONARE)

2° Problema] se provo a richiamare il plugin R (R è installato su
windows)-->

Grazie in anticipo.
