after agreeing to receive push-notification the app crashes iphone - ios

Question

notification for my app, and i couldn't figure out, why the app crashes after the push-notification dialog. If I run the app again after the crash it will work fine, and the token will be registered in my DB
Would really appreciate your help with this problem.
Thanks in advance
