Yes, some very critical info ;)
BackbufferToTex saves the backbuffer to a texture, not an image.
To save a screenshot you can use GrabPixmap and save the pixmap created with that function instead of the using a blank pixmap.
Also try to avoid to save with Alphachannel because this may break the result slightly.
