### Bug in eigenmatrix command?

I'm new to sage, so this might be my bad, but I think there is a mismatch between complex conjugate eigevector/values in what the eigenmatrix_right() returns:

In my case:

```
J = matrix(CDF, [[-2.53634347567, 2.04801738686, -0.0, -62.166145304], [ 0.7, -0.6, 0.0, 0.0], [0.547271128842, 0.0, -0.3015, -21.7532081652], [0.0, 0.0, 0.3, -0.4]])
D, P = J.eigenmatrix_right()
```

D has two (almost) purely imaginary complex conjugate eigenvalues.
I thought

```
A1 = J * P
```

and

```
A2 = P * D
```

should be identical, but the complex conjugate eigenvalues are interchanged, so two columns in A1 and A2 differ by a multiple of (-1).
In my case things work ok if I interchange D[1][1] and D[2][2].

Am I missing something?
