Errors in browser console for missing angular-sanitize.min.js.map

[vanguard737]

When I point Chrome to my PPC 1.3.9 instance and open the developer console, I see the following error:

DevTools failed to load source map: Could not load content for https://<my url>/static/1.3.9/js/lib/angularjs/1.2.14/angular-sanitize.min.js.map: HTTP error: status code 404, net::ERR_HTTP_RESPONSE_CODE_FAILURE

And sure enough, that .map file is absent from the repo under pypicloud/static/js/lib/angularjs/1.2.14.

AFAICT, this error message is completely benign, and this is probably the lowest-priority issue you'll see all month :).
