The amount of blurring achieved by a gaussian blur is specified by the
standard deviation of the blurring kernel not the size of the blurring
kernel. This probably means that GIMP and Photoshop use different ways
of computing the standard deviation used from the user specified

Using the size of the kernel (which probably is ~2.5x the standard
deviation) might be leading to behavior similar to what GIMP is doing.
