UIPresentationController crash just points to AppDelegate

Any ideas where I could start to investigate from the following crash report? Crashed: com.apple.main-thread 0 UIKit 0x18d005640 __56- [UIPresentationController runTransitionForCurrentState]_block_invoke + 460 1 UIKit 0x18cf27aa8 _runAfterCACommitDeferredBlocks + 292 2 UIKit 0x18cf1ae5c _cleanUpAfterCAFlushAndRunDeferredBlocks +
