Can you provide a minimal UX example that I can test the defect and fix?

Yes sure, see the comments on the sample code:

<App>
	<StatusBarBackground Dock="Top"/>
	<JavaScript>
	var Observable = require("FuseJS/Observable");
	var GeoLocation = require("FuseJS/GeoLocation");

	 
	/***
     To get the Blue Location Marker (pull request #1122)
     How to reproduce:
     1/ click on the blue button displayed at your location
     => Crash

     With the fix : no crash.
	*/
	var timeoutMs = 5000;
    GeoLocation.getLocation(timeoutMs).then(function(location) {
    }).catch(function(fail) {
        console.log("getLocation fail " + fail);
    });


	module.exports ={
		
	}

	</JavaScript>
	<Panel>
		<NativeViewHost >
	            
	        
	            <MapView ux:Name="map" ShowCompass="true" ShowMyLocation="true" ShowMyLocationButton="true"   AllowScroll="true" >
	               
	            </MapView>            
	    </NativeViewHost>

</Panel>
</App>
