Python Wand, Color.red_int8 (blue and green too) always returns 0

Question

Running this simple example:

with Color('#f00') as red:
    print red
    print red.red_int8, red.green_int8, red.blue_int8

the first print shows srgb(255,0,0) as I expected. For the second print I expected to get 255 0 0 but it actually prints 0 0 0.

At least the documentation states:

blue_int8

(numbers.Integral) Blue as 8bit integer which is a common style. From 0 to 255.

could this be a bug or am I doing something wrong here?

EDIT Tryed it again with Python3 (above was Python2.7) and it's the same:

>>> from wand.color import Color
>>> x = Color('#f00')
>>> x.red
1.0
>>> x.blue
0.0
>>> x.green
0.0
>>> x.red_int8
0
>>> x.blue_int8 
0 
>>> x.green_int8
0
>>>

$ python2.7 -m wand.version --verbose
