Silent errors in ember components

Recently i have found strange behaviour in my application

if i have a problem in component, i don't receive any errors, application loads with blank screen and after several tens seconds i receive a deprecation: [deprecation id: ember-views.render-double-modify] without any clues what is the real problem

it might happen when i pass non existing closure action to component, or event if i manually throw error in computed property in component

it happens in all recent versions of Ember (2.4.6+)

I can not reproduce such behaviour in empty application, so probably problem in my application or addons, but i have no idea how to find what catches errors.

Any ideas how to find source of the problem?
