Registration for opportunities shows empty page on Wordpress Frontend

On Wordpress 4.6 with CiviCRM 4.7.10 and CiviVolunteer 4.1.2 one can register as volunteer through the frontend IF no opportunities are set (?page=CiviCRM&q=civicrm/volunteer/signup&reset=1&needs[]=1&dest=event works)

But if you define some volunteer opportunities the page (?page=CiviCRM&q=civicrm/vol/#/volunteer/opportunities?project=1&dest=event&hideSearch=always) shows up empty (4 xhr queries are done without a glitch)

No JS errors are logged to the console.

Expected behaviour would be to show the opportunities to the user.
