Rotation issue: DetailView is empty

I develop a iPad App with has one UISplitViewC开发者_StackOverflowontroller. In the DetailView is a TabBarController with some NavigationControllers.

My Problem is that: The Detail View is Black when i start the App in Landscape, Home Button Right. When i turn the iPad around that the Home Button is on the left side, the Detail View shows content. When i start the App in Landscape, Home Button Left all works fine.

I tested several things, like rebooting the device or modify the shouldAutorotateToInterfaceOrientation, but nothing helped.

iOS 4 Problem. Fixed in newer Versions.
