In itunes review the app got crashed when opened, but not able to reproduce the bug on my end. Tried with adhoc mode as well. what could be possible reason

Hello,

My app got rejected, as per review app got crashed when opened. I tried to reproduce the crash but not able to. Tetsed under simulated ipv6. As per crash log which on symbolicating, show applicationDidRecieveNotification which had just one NSLog() as the source of crash.


Kindly guide me how can i reproduce the bug, so i can end up solving and uploading it on App Store.
