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 18.104.22.168.
Try reproducing this on 22.214.171.124 please and let us know if you still get the crash by reporting to firstname.lastname@example.org with a log file that captures the issue.
