Might be related to msabramo/requests-unixsocket#24 as Fedora 26 already uses python2-requests-2.12.3-1.fc26. Although pylxd upstream only has python-requests-2.12.1 and python-requests-2.12.2 excluded in requirements.txt so it might be something different.
Issue fixed with 65ec0d8a6f897ad121cd50ab70c46d181a118882 (python-requests_unixsocket-0.1.5-2) thanks to the patch from msabramo/requests-unixsocket#27
