Comment 4 for bug 1811107

this can easily be reproduced in master by stoppingat the "add ssh keys" page at the first user journey. it doesn't always happen, but a few page reloads should show it.

The reason for it is that the $scope.user in intro_user.js can be null, because UsersManager.loadItems calls this._loadAuthUser() but doesn't actually way for it to complete, so the _authUser can still be null when the function returns (and gets propagated as such).
