AttributeError: 'HttpUrl' object has no attribute 'proxy_type'

[gr1ev0us]

The problem appears when i chek local web-site: linkchecker --ignore-url=^mailto: www.sintez.dev

I've tried to change 'url_data.proxy_type' to 'url_data.proxytype', but it creates a new error in /usr/local/lib/python2.7/dist-packages/requests/sessions.py: AttributeError: 'set' object has no attribute 'setdefault'
