reloading problem with an angularjs app with default ngRoute-ing

I had the problem that my angularjs app (using a default route, e.g. `.otherwise({redirectTo:'/somewhere'})`) doesn't get reloaded - it shows "App updated. Reloading app..." - but the iframe stays empty.

I guess it has something to do of how the browser handles reloads of URLs with a fragment. I had to put `contentWindow.location.reload()` to make it work.
