Stepping through JavaScript code in App Manager?

Question

I am using Firefox App Manager to upload a packaged app to a Firefox OS phone, a KEON.

Now, when I go into the debugger and click on one of the source files, then I see:

[no source]

Is it even possible to step though source code using App Manager? If so, how?

what version of Firefox OS are your running? What version of Firefox are you running? Also try to download https://github.com/robnyman/Firefox-OS-Boilerplate-App and see if you can step through its code. — Jason Weathersby, Jun 02 '14 at 15:29
@JasonWeathersby The KEON is running *Boot2Gecko OS 2.0.0.0-prerelease.* Some days ago, I tried out several of the versions [available for download](http://downloads.geeksphone.com/), and that one worked. Other versions that I tried had issues which affected my app. The latest stable version for the KEON I think is 1.1. As for Firefox, it's *29.0.1 on Windows 7 x64.* Following your suggestion, I tried the [boilerplate app](https://github.com/robnyman/Firefox-OS-Boilerplate-App), and there stepping through code works! — feklee, Jun 02 '14 at 15:45
I have seen this happen sometimes when their is an error in loading all the js files. Can you try to open the app in Firefox (meaning no app manager, just open your index.html) and then launch the tools and check the console. See if it reports an errors. — Jason Weathersby, Jun 02 '14 at 15:50
@JasonWeathersby I now found out that if I remove `"type": "privileged"` from `manifest.webapp`, then stepping works. Looks like a bug to me. — feklee, Jun 05 '14 at 10:10

With help by @JasonWeathersby I figured out that the problem is triggered by:

The app is privileged. Excerpt from manifest.webapp:
```
"type": "privileged"
```
The Keon is running Firefox OS 2.0.0.0-prerelease.

Source code shows up either if I remove "type": "privileged", or if I install 1.3 on the Keon.
