It looks like it is crashing in your code not in AppKit code (the
backtrace may be a little confused if a tail-call optimization is
taking place). It appears that something is attempting to access a
NULL pointer in your code.
Use atos and/or gdb to understand what is going on at/around 0x0031b9a
in your application (you hopefully have a symboled version of what you
shipped to customers).
Review the following for information on how to work with a crash report log...
