Certificate error: no appropriate commonName or subjectAltName fields were found

Hi! : )

New to bazaar, whether dead or not ; ) I just installed it last night. If this question doesn't belong here please give a hint as to where it should go. Thanks.

I tried to download the source for dudle according to its website and typed in a terminal:

$> bzr branch https://dudle.inf.tu-dresden.de/unstable/ dudle

But the answer was:

        bzr: ERROR: Certificate error: no appropriate commonName or subjectAltName fields were found

I have "duckduckgoed" a little and searched docs, faqs and questions on this site but have not been able to find an answer. I also found something about it at http://bugs.python.org/issue1589 but it is way beyond my knowledge : (

Could some kind soul point me in the direction to be able to download dudle code?

Thanks a lot.
