Recieving message "SIGKiLL" using iOS5 iPhone 4S


In Chapter 15 I got a big problem, which i could not solve yet.
All my research failed.

I used the Xcode 4.1 to create the Window Bases Application.
After that I created the project in Xcode 4.2.1 (both versions installed).
When I came to chapter 15 I typed all the code in my application, which is a bit different to the Homepwner.
But in the end the App is not able to restore my saved data. When I start the App again it cannot open the save data. The compiler receives the message “SIGKILL” and the iPhone gets a black display is frozen in the app. When I press the standby button the iPhone works fine again.

Later I tried the same with the downloaded Xcode Project Homepwner in Chapter 14 and I tiped in all the code and in the end I´m receiving the same message.

This is the only information I got from the debugger:

warning: Unable to read symbols for /Users/Sn0wfreeze/Library/Developer/Xcode/iOS DeviceSupport/5.0.1 (9A405)/Symbols/System/Library/AccessibilityBundles/QuickSpeak.bundle/QuickSpeak (file not found).
warning: No copy of QuickSpeak.bundle/QuickSpeak found locally, reading from memory on remote device. This may slow down the debug session.

Hope you can I help me :S
