Anything stick out to anyone?

Can you post a full Apple crash report for this? See Posting a Crash Report for advice on how to do that.

@eskimo thinking it is a JSON.Stringify() call based on the report but not sure if it my code or the framework's code.

Hmmm, that crash report got munged somewhere along the way. Consider line 31, which should be:

0   libsystem_kernel.dylib        	       0x1e29f8c84 mach_msg2_trap + 8

But something inserted hard line breaks [1], so I got:

0   libsystem_kernel.dylib        	       0x1e29f8c84 mach_msg2_trap 
+ 8

Can you check whether these hard line breaks are in the original crash report? Or perhaps your redaction introduced them?

[1] Normally my first suspect would be DevForums itself, but I ran a quick test and DevForums seems to be doing the right thing here (for once :-).
