iOS 9.1 crash

We encountered a large number of crashes reported by Crashlytics, but our development team was unable to reproduce it so far. It seems to happen more frequently on iOS 9.1 (we had this crash before as well, but the number has dramatically increased since 21st of October - launch date of iOS 9.1).


The stacktrace is not very helpful, but hopefully somebody else encountered something similar:

Please let us know if you have any thoughts about how this crash can be reproduced/fixed.


Thanks!
