E_INVALID_PAR_TYPE error while loading

In raising this issue, I confirm the following (please check boxes):

• I have read and understood the Wiki. Especially deploy and configuration articles.
• I have checked that the bug I am reporting can be replicated, or that the feature I am suggesting isn't already present.
• I have checked the pull requests tab for existing solutions/implementations to my issue/suggestion.
• I realise that server-side connectors are provided by various contributors. The implementations are vary due to programming language features/limitations or other factors. Thus a particular connector may not implement, or partially implement, the API features.
• I realise that any changes in configuration options and/or plugin parameters affect the plugin behavior. I specified all the differences from defaults in details.

I use the following server-side connector (check one):

On one deployment I have this annoying error:
E_INVALID_PAR_TYPE
I can't pinpoint exact culprit here but I've manage to find that in libs-main.js there are many checks and one that looks for a being [object Object] fails because it receives json string instead of json object. It looks like it wasn't converted on some point because when I take this string and put it through JSON.parse it converts without any hassle.
From what I understand it tried to load some cldr components...but because libs-main.js is minified it's hard to get where the problem starts exactly. Internet suggested that it could be something with globalize loading cldr but I don't know where to look for it...

Because I have this issue only on one machine I'm guessing it could be related to some permissions because that's what stands different on this one machine. Besides that I have no idea. Configs and such are the same on each machine.

I'm pretty sure it's related to #320

Not sure if that is the correct way of doing it but I found that changing filemanager.js to force creation of JSON object:
return [].slice.apply(arguments, [0]).map(function (result) { if(typeof result[0] == 'string') result[0] = JSON.parse(result[0]); return result[0]; });
makes this error go away and load file manager.
Could you tell if that change does not break anything?

Thanks @Draghmar. This resolves my issue.
