Haven't seen this crash since the latest release (which was 5 months ago), I guess the problem was in missing synchronization.

Have you solved this problem? What is the reason. thank you

I haven't seen this crash since June (in my app where this library is used) and the last thing I did was synchronizing all public methods, so I guess that was the problem.
