Steps to Reproduce

1. Go to tutorial template, click "Use this template" > "Create a new repository".
2. Enter repo name (I used rtd-tutorial-LVS4), leave other settings at default values, click "Create repository".
3. Go to RTD dashboard, click "Import a Project", click "+" next to the repo, accept defaults, click "Next". (Build triggers automatically.)
4. Go to Builds page, open the build, "View raw". Log contains:
