Yeah, OK, that sort of behavior in MAGMA is really annoying. I remember running into problems like that when computing Selmer groups... Anyways, just out of curiosity do you think SAGE should default to "proof = True" (like Magma claims to do, but I've heard doesn't really) or "proof = False" (like PARIA) when computing class groups? Right now, SAGE defaults to proof = True for that, but maybe it shouldn't? Please share your thoughts. The difference in speed between proof True and proof=False is vast in this case.
