I add additional logs

        log.info('version_slug %s' % (version_slug))
        log.info('project %s' % (project))
        log.info('project.versions %s' % (project.versions))
        log.info('request.user %s' % (request.user))
        log.info('public %s' % (project.versions.public(request.user)))

And get

[26/Jan/2017 02:39:34] INFO [readthedocs.core.views.serve:149] version_slug latest

I fix it

def serve_docs
    ...
    #version = project.versions.public(request.user).get(slug=version_slug)
    version = project.versions.get(slug=version_slug)

Marking it as Community Effort. Explanation at this comment: #2281 (comment)

@NikitaEgorov the slugs are unique, I don't know how you ended with two projects with the same slug.

I was faced with the same error. Thank you @NikitaEgorov for solving the problem
