Use of navCtrl.setRoot more than 10 times freezes the app

[EugeneSnihovsky]

Short description of the problem:

Simple project with two pages and buttons that redirect on each other with navCtrl.setRoot(PageName).
On 11 click on android device app freezes forever.
On 11 click on chrome I see black screen and can do nothing.

What behavior are you expecting?

I want to navigate in my app from page to page with navCtrl.setRoot infinite times.

Steps to reproduce:

1. git clone -b ER-1_freeze_after_multi_navigation https://github.com/EugeneSnihovsky/ionic2-for-errors.git
2. cd ionic2-for-errors
3. npm install
4. ionic serve
5. Navigate from home to settings page more than 10 times.

Page code (second page similar)

'use strict';
import {NavController} from 'ionic-framework/ionic';
import {SettingsPage} from '../../main/settings/settings.page';


import {Page} from 'ionic-framework/ionic';

@Page({
    templateUrl: 'build/components/main/home/home.html'
})

export class HomePage {
    private navCtrl: any;
    constructor(navCtrl: NavController) {
        var self = this;
        self.navCtrl = navCtrl;
    }

    open(name) {
        this.navCtrl.setRoot(SettingsPage);
    }
}

Same problem here, but whatever number of navigation pages.

Using this.nav.push or using this.nav.setRoot when I close an Alert causes black screens on Chrome (most of time).

Thanks for the report! What really helped was "Navigate from home to settings page more than 10 times.", and the 10 helped figure out what the issue was. Should be fixed in the next release, thanks!
