@Chris

Sorry for taking so long to answer this.

The problem is that checkbox-editor uses a packager template to generate have the version number, revision, etc. available in a python module that can be used, for example, to display that information in the `Help -> About` menu. When the checkbox-editor branch is created, that template (checkbox-editor/build.py.mako) hasn't been yet rendered and the python module isn't available.

To fix that you can run:
$ packager render
. render:checkbox_editor/build.py.mako

after that, you'll see that checkbox_editor/build.py is available and that you can launch checkbox-editor from the branch as follows:
$ PYTHONPATH=. ./bin/checkbox-editor
