@KonamiWu Just a stack trace isn't very helpful. Can you post some log output?

@hansemannn That stacktrace doesn't really help. It just shows that the library called back into your code, which then did some stuff that caused a crash. My gut tells me that it's something to do with dispatch queues. By default the library uses the main queue to dispatch callbacks to.
