I'm getting a lot of unexplained crashing occuring with the PNDispatchHelper. I get a EXCBADACCESS. This problem seems to occur when I updated to the latest SDK version 220.127.116.11.
Try reproducing this on 18.104.22.168 please and let us know if you still get the crash by reporting to email@example.com with a log file that captures the issue.
