Good catch, I can try, but since I'm not able to reproduce at will, I'll have to wait and see if I receive any such crashes from our production apps.

https://github.com/wix/react-native-navigation/commit/085b3c9c901107c0da1b47dea6f042f43958b206 seems haven't fixed this issue, we also have one hundred uses encounter this problem.
But now, I decided to upgrade our RNN version to 2.0, hope it will work excellently.

@sapjax
Does upgrading the RNN version to 2.0 made this kind of issues go away?
Thanks!
