[Qgis-developer] [RendererV2 Stand alone script] - returning None

[Danilo da Silveira Figueira]

Hi all,

I´m planing to use some features of the Qgis in my python script.
i am using the function QgsVectorLayer.loadSldStyle that returns true but
the result of the QgsVectorLayer.rendererV2 not works when i am using the
script outside of the QGIs. How can i solve this?
I already have tried adding the following calls to my script:

QgsApplication.setPrefixPath("qgis_path", True)
QgsApplication.initQgis()
app = QgsApplication([], True)

Thanks u all.
