On which line? What is the exception text?
You can get a FormError exception from dns.query.xfr() if the server replies
with no resource records (indicating it rejected your AXFR request).
I've just encountered exactly this behaviour. I think the conditional in
query.py needs to be separated so distinct exceptions are raised for 'no
answer' and 'bogus answer':
if not r.answer or r.answer[0].name != oname:
raise dns.exception.FormError("No answer or RRset not for qname")
