Nightly build failed to install due to failure in `gitlab-pages --version`

I just upgraded my test instance with this config:

pages_external_url "http://pages.example.com/"
gitlab_pages['enable'] = true

gitlab-ctl reconfigure failed because :

There was an error running gitlab-ctl reconfigure:

version_file[Create version file for Gitlab Pages] (gitlab-pages::enable line 58) had an error: RuntimeError: Execution of the command `/opt/gitlab/embedded/bin/gitlab-pages --version` failed with a non-zero exit code (1)
stdout:

I would think the --version command-line shouldn't require config validation?

$ /opt/gitlab/embedded/bin/gitlab-pages --version

@jaime @vshushlin This looks like it was introduced in gitlab-pages!532 (merged).
