Ionic 2 beta 10 navigation doesn't work with Android emulator

Hi, since I’ve upgraded my Ionic 2 app from beta 9 to beta 10, navigation on an Android emulator (Genymotion) no longer appears to work, instead resulting in the app freezing. Has anyone else experienced this? Thanks!

Here’s the standard push nav code that has been working before but no longer does for me in beta 10:

this.nav.push(PageName);

Post your code, not just a statement.
