Sencha Cmd 5.0.2: ExtJS locale file loaded twice

I am experiencing a problem, where the ext-locale file is loaded twice.

To reproduce the problem, create a new sencha app:

Code:

sencha generate app MyTestApp /path/to/app

then switch to the german locale, by modifying your app.json to require "ext-locale" and set "locale": "de".

Code:

{
    "name": "TestApp",
    "requires": [
        "ext-locale"
    ],
    "locale": "de",
    "id": "56be4074-63c3-44b7-bee5-2550dc389407"
}

and build the app: If you load the app, you will see that ext-locale-de.js is loaded twice. Once with _dc-Parameter and once without.

I don't know how it is for other locales, but for the german locales this totally breaks Ext.util.Format.number() as this is rewritten for the german locale:

Code:

        Ext.util.Format.__number = Ext.util.Format.number;
        Ext.util.Format.number = function(v, format) {
            return Ext.util.Format.__number(v, format || "0.000,00/i");
        };

Executing the above snippet twice will result in a maxium call stack size exceeded error, since it causes an endless loop when calling Ext.util.Format.number().

Maybe there is someone around who has an idea on how to temporarily fix this?
