500 when calling setTitle using angular 2 titleService and server side rendering

I have a problem with server side rendering using angular 2 and titleService.

My code looks like this

import { Component } from '@angular/core';
import { BrowserModule, Title } from '@angular/platform-browser';
import { Router } from '@angular/router';

@Component({
    selector: 'app',
    templateUrl: './app.component.html',
    styleUrls: ['./app.component.css'],
    providers: [Title]
})

export class AppComponent {
    constructor(private titleService: Title) {
        titleService.setTitle("Setting the title...");
    }
}

This works fine using client side rendering but when reloading the page I get this error:

Exception: Call to Node module failed with error: TypeError: Cannot create property 'title' on string ''

Any ideas why this occurs?
