Docker file type cannot parse multiline LABEL section in Dockerfile

[jakubka]

My Dockerfile looks like this:

FROM python:3.5

LABEL org.label-schema.name="aiohttp" \
      org.label-schema.description="aiohttp reference app"

ENTRYPOINT python -v

when trying to manipulate it with:

with dockerfile f when path = "Dockerfile"
do addOrUpdateFrom latestImageName

This is an error I'm getting and a full call stack:

I confirmed that the docker file type works fine if the LABEL section only has one line. Also, spanning instructions across multiple lines in other sections (RUN for example) works fine as well.
