Registering Custom Protocol for Windows Phone 8 App WebBrowser Control

Question

I'm searching for a way to register a custom protocol for Windows Phone 8. I tried to register a custom protocol with WebRequest.RegisterPrefix("xxx://", this) but this will not work for the WebBrowser control. Since our protocol scheme is no valid uri the app will just crash if it try to navigate (via location.url='xxx://this-is-no-valid-uri').

I hope anyone can spread light into the darkness ;)

EDIT: Here is my test project. I think this is a major bug because you can force every app to crash with just a simple JavaScript statement.

I finally got a Solution for my Problem, you need to register a own UriParser.

My UriParser:

public class MyUriParser : UriParser
{
    public MyUriParser()
    {

    }

    protected override string GetComponents(Uri uri, UriComponents components, UriFormat format)
    {
        return "";
    }
    protected override bool IsWellFormedOriginalString(Uri uri)
    {
        return true;
    }
    protected override void InitializeAndValidate(Uri uri, out UriFormatException parsingError)
    {
        parsingError = null;
    }
    protected override bool IsBaseOf(Uri baseUri, Uri relativeUri)
    {
        return false;
    }
    protected override string Resolve(Uri baseUri, Uri relativeUri, out UriFormatException parsingError)
    {
        parsingError = null;
        return "";
    }
}

Registered via:

if (!UriParser.IsKnownScheme(SCHEMENAME_0))
    UriParser.Register(new MyUriParser(), SCHEMENAME_0, 80);
