Hi, we working on Huayra GNU/Linux a derivated distro from debian. At this time our 3.1 release is made over jessie.
I found this behavior on the repository configuration screen of synaptic. we solved it adding the correct *.info and *.mirrors files into /usr/share/python-apt/templates i know that is a very old bug, but maybe this info can be useful for other people.
