handlebarjs failing on non-debug deployments

[adamlwgriffiths]

When deploying to non-DEBUG builds, handlebarjs fails to inject handlebar code from a template file. I'm at a loss to explain why, as it works locally.

Ie, when running the following code:

{% handlebarsjs 'handlebar_template' precompile %}

Locally I get the following result:

<script type="text/x-handlebars-template" id="handlebar_template">
...

But in production I get nothing. I know it's not being stripped out by the server, as I can manually include the locally output tags inside a django {% verbatim %} tag and it works.
