Strange crash when presenting modal UIViewController

I have seen this brief report several times. It is extremely random and rare, and I cannot understand it. All I do is modal view controller using the following code

ComposeController *newcontrol = [[ComposeController alloc]initWithMode:1 withNIB:@"ComposeController"];
newcontrol.delegate = self;

UINavigationController  *holder = [[UINavigationController alloc] initWithRootViewController:newcontrol];
[self presentViewController:holder animated:YES completion:NULL];

Somehow this leads to this completely by accident:
