Hi everyone,

I've found a strange report in the crash logs of our app.

Code:

31 libdispatch.dylib              0x181e2e8b8 (Missing)
That occurred 17 times for a single user, so it seems quite deterministic. The device is an iPhone 5s with iOS 9.2.1. Any idea on what it could be?

Thanks in advance!
