Comment (by davidloeffler):
Here's a bug I found while testing your Atkin--Lehner ticket:
{{{
sage: f = Newforms(Gamma1(25), names='a')[1]
sage: eps = f.character()
sage: f.twist(eps)
---------------------------------------------------------------------------
TypeError Traceback (most recent call
last)
...
TypeError: No compatible natural embeddings found for Complex Lazy Field
and Number Field in a1 with defining polynomial x^8 + 5*x^7 + 11*x^6 +
10*x^5 + x^4 + 10*x^3 + 26*x^2 - 10*x + 1
}}}
