Nectar

We received a GitHub pull request with a fix for this issue before the issue was filed, and the pull request is already merged. I am filing it here as well so we can track that we have an unreleased bug fix.

The rest of this description is quoted from the pull request.

When using basic authentication for the url to fetch and using a proxy without authentication, all the authentication gets stripped away when the proxy_username exists in the config file /etc/pulp/server/plugins.conf/yum_importer.json but is empty. This is because in threaded.py the code checks if proxy_username == None, which is untrue (it is an empty string). Since

variable = ''
if variable:
do_something
evaluates works as well, this is the better option in my opinion.
