docker.image_present fails on state.pkg call when building with SLS

Description of Issue

During a run of docker.image_present using the "sls" option to build from another SLS file, it fails when calling "state.pkg" on the file "salt_state.tgz".

Setup

SLS files (this is just a contrived example for demonstration)
sls_build/init.sls

Build image with SLS:
  docker_image.present:
    - name: sls_build
    - sls: sls_build.image_build
    - tag: latest
    - base: 'centos:7'
    - pillar:
        symlinks:
          - /usr/local/bin/a
          - /usr/local/bin/b
        target: /usr/bin/grep

sls_build/image_build.sls:

{% for symlink in salt['pillar.get']('symlinks') %}
Create symlink {{symlink}}:
  file.symlink:
    - name: {{symlink}}
    - target: {{salt['pillar.get']('target')}}
    - makedirs: True
    - force: True
{% endfor %}

Steps to Reproduce Issue

Run: salt-call state.sls sls_build

Output:

local:

          ID: Build image with SLS

        Name: sls_build

Looking at the log, I see this as the actual failure:

I can provide full debug output if needed.

Reproduce the failure with salt-call state.sls sls_build using docker.image.present and the sls_build.image_build SLS example. Trace the docker.image.present path through its state.pkg call for salt_state.tgz and inspect the reported retcode 2. Done means the SLS-based image build completes without the state.pkg failure.
