MathieuC Error?

If I calculate:

  MathieuC[MathieuCharacteristicA[0,0],0,0]

I obtain a result of 1 but if I use instead:

  MathieuC[MathieuCharacteristicA[0,0.000001],0.000001,0]

I obtain 0.707106.

The correct value is Sqrt[1/2] so it looks as if the normalisation is
wrong for q = 0. Is this a known issue or am I doing something wrong?
