App crashes very rare on start up

I have a strange problem with my app, sometimes, very rare in fact, when run on iPhone4, it crashes right at the beginning, I got the crash log, but I really can't make anything of it. I'm kind of stuck, where should I look? Here is the log:

0   libsystem_kernel.dylib          0x34c96a1c __pthread_kill + 8
1   libsystem_c.dylib               0x328ee3b4 pthread_kill + 52

26  GraphicsServices                0x353504c4 GSEventRun + 56
27  UIKit                           0x35597d62 -[UIApplication _run] + 398
28  UIKit                           0x35595800 UIApplicationMain + 664
29  My App                  0x00002118 0x1000 + 4376
30  My App                  0x00002084 0x1000 + 4228

I was not able to find any pattern for the crash, it simply happens like maybe once in 30-40 app start-ups. What beats me, beside the fact that I don't know how the interpret the crash log, is why this happens so rare, with no apparent reason?

You need to symbolicate that crash log before you can see exactly which part of your code is crashing.
