Python indent error range off when followed by comment

[differentmatt]

def fn():
  x = 45
  # Bummer
    x += 5
  return x
return fn()

[ { ofs : 32, row : 3, col : 2 }, { ofs : 34, row : 3, col : 4 } ] expected
[ { ofs : 21, row : 2, col : 2 }, { ofs : 38, row : 2, col : 19 } ] actual

May be problem in Python parser.
