--- Comment #3 from Chris Sherlock <chris.sherlock79 at gmail.com> ---
I debugged this, and it isn't an issue with premultiplied alpha as far as I can
see. In SvpSalGraphics::getPixel, the value of data is 0x0000 

 unsigned char *data = cairo_image_surface_get_data(target);

data[SVP_CAIRO_ALPHA] is 0
data[SVP_CAIRO_BLUE] is 0  
data[SVP_CAIRO_GREEN] is 0
data[SVP_CAIRO_RED] is 0
