I couldn't find a universal way to break on that message, however, based on a comment in the apple dev forums, I was able to figure out a cause I haven't seen turn up on stackoverflow or in google.

My app has the status bar initially hidden so it isn't there when the default.png is displayed. In application:didFinishLaunchingWithOptions: I was calling [application setStatusBarHidden:NO withAnimation:YES]. Commenting out that call removed the message. It didn't matter if the animation flag was NO. Wrapping this cal in a dispatch_async also removed the message.

I used to get the same debug message and could not find any sort of answer, on a off chance I set the Split Keyboard setting to OFF. Settings - General-Keyboard-Split Keyboard - OFF. So far it has worked for me. Co-incidence... IDK.
