I have users email me stack traces when my app crashes on their device. Prior to iOS 6 they looked like this:
CRASH: NSInvalidArgumentException (*** -[__NSArrayM
Do you have any iOS 6 betas installed, by chance? I ran into this same problem.
This question helped me.
The OP mentions the wrong file to use in his EDIT.
This post has all the info required to get this working:
Using atos to determine crashed method name with dSYM
Clear instructions on where to find the correct file to run with atos:
Atos cannot get symbols from dSYM of archived application
Make sure to use the correct architecture; I was trying to use armv7, but I needed to specify arm64
