ios - Instruments show leak in main.m (Xcode 4.3.1)

Question

I am developing an app using ARC When profiling my app in instruments for memory leaks it shows leaks at the following function:

#import <UIKit/UIKit.h>

#import "AppDelegate.h"

int main(int argc, char *argv[])

{
    @autoreleasepool { 
       return UIApplicationMain(argc, argv, nil, NSStringFromClass([AppDelegate class]));
    }
}

Does this indicate a problem somewhere else in my code?

This is the stack trace

It seems to be a bug in the iOS 5.1 framework: https://devforums.apple.com/message/630695
