Comment(by mvngu):
With both patches, I'm seeing this doctest failure:
{{{
sage -t -long devel/sage-exp/sage/rings/number_field/galois_group.py
**********************************************************************
File "/scratch/mvngu/release/sage-4.1.1.alpha0/devel/sage-
exp/sage/rings/number_field/galois_group.py", line 171:
sage: NumberField(x^3 - 2, 'b').galois_group()
Expected:
Traceback (most recent call last):
...
TypeError: You must specify the name of the generator.
Got:
Galois group of Galois closure in b0 of Number Field in b with
defining polynomial x^3 - 2

Incidentally, after running all doctests a second time, I get a doctest
failure in the plotting code:

This failure didn't appear after running all doctests for a third time.
Hmmm... strange.
