"ValueError: Extra data: line 1 column 5 - line 2 column 1 (char 4 - 25)" with Discogs plugin

I'm using Archlinux and beets 1.3.7-1 from the community repository with python2-discogs-client 1.1.1-1 for Discogs support. Tried importing music today which failed with the following backtrace:

Bisection of my config reveals the issue goes away if I just deactivate the Discogs plugin. Any ideas what exactly might be the culprit?

edit: Forgot to attach my (mostly unchanged) config:

There has been recent commits posterior to the 1.3.7 release related to a Discogs API change.
So you can wait for next version before reactivate the plugin, or grab master branch.

Thanks, tried again with the master branch and Virtualenv and it works as expected.
