Parsing stack-trace of a crash

Parsing stack-trace of a crash

In one of my apps I have a very common crash. I have this report in
bugsense : *** -[__NSArrayM objectAtIndex:]: index 0 beyond bounds for
empty array
And this stack trace after symbolication:
0 CoreFoundation 0x3796b2a3 + 162

I understand that the problem is in an empty NSMutableArray but I can not
locate the place or at least a potential place in the code. I know that
this trace does not say to much but I will appreciate any idea or
direction that you can get from it that I might not be aware of.
Thanks Shani
