If you place an empty file called "debug", in the bin directory where PDFRead is located, the images that were used in the lrf will be left behind. Open one and see it that "white space" is there too. Remember, the aspect ratio is retained, so either the top-bottom will have a white border or left-right; but not both!
However, if it is that, check the border to see if there isn't some spot or page number that STOPS the cropping of the .pdf to the text edge.
Just food for thought.
