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 after upgrading to iOS 9 or iOS 9.0.1.
Here is the stacktrace from Crashlytics:

Does anybody know about what could be the cause of this crash? If so, is there a fix/workaround for it?
Thanks,
