Saving renderTexture


I am trying to save the content of a renderTexture to a file.
I basically use code from the examples as listed further down my post.
Everytime I call"test") i get an error message that tells me that there is no data in the image.
* ERROR: Texture does not contain image data, cannot save to file 'test'
Any hints on what I am doing wrong?
I also put the texture on a quad to see if there is actually something going wrong, but the desired render is diplayed fine on the quad.
Here is my code:
                # Create render texture for sending screenshots
                self.renderTexture = viz.addRenderTexture()
                # Create render node as camera
                self.renderNode = viz.addRenderNode(size=(800,600))
                # Do not inherit view/projection settings from main window
                # Set FOV for renderTexture camera
                # Render to renderTexture feed texture
                #NOTE: I also tried renderNode.setTexture here, but that didn't work either

                # Only render once per frame, in case stereo is enabled
                #add a texture quad
                quad = viz.addTexQuad()
                #add the rendertexture to the texturequad
                quad.texture( self.renderTexture )
                #position the texture quad
                #NOTE: The texture renders fine on the quad
                #This call fails with above error
