Comment (by pbruin):
In !SageMath 7.3.beta7 with #18061 merged, one gets yet another error:
{{{
sage: f = Newforms(Gamma1(13), 3, CyclotomicField(40), names='a')[0]
sage: f.atkin_lehner_eigenvalue()
Traceback (most recent call last):
...
TypeError: unsupported operand parents for '/': 'Cyclotomic Field of order
52 and degree 24' and 'Cyclotomic Field of order 40 and degree 16'
}}}
