title: Ember.js sometimes not showing errors
body: <p>Sometimes the ember app crashes, normally when I do something at an earlier stage, but I haven't really seen a pattern - and no error is logged to the console.</p>
  
  <p>I can see the error if I set a break point to <code>TRY_CATCH_ERROR.error = e;</code> somewhere in the guts of the rendered app - but there has to be a simpler way I guess.</p>
