[1.4] Kerning values can't be rounded ('DoodleKerning' has no attr '_kerning')

jens

When I try to round the kerning:

f = CurrentFont()
f.kerning.round(1)

I get this:

Traceback (most recent call last):
  File "ChangeUPM.py", line 3, in 
  File "lib/fontObjects/robofabWrapper.pyc", line 448, in round
  File "lib/fontObjects/doodleKerning.pyc", line 52, in round
AttributeError: 'DoodleKerning' object has no attribute '_kerning'

Other kerning operations work, e.g.

f.kerning.scale(3)

or

print f.kerning.keys()

And I think kerning.round() worked in 1.3 ...
