Warning, wait_fences: failed to receive reply: 10004003 while using an UIAlertView

I'm getting the following warning..

wait_fences: failed to receive reply: 10004003

I've calling the alert view from applicationWillEnterForeground, however the warning occurs after didDissMissWithButtonIndex.

- (void)alertView:(UIAlertView *)alertView didDismissWithButtonIndex:(NSInteger)buttonIndex
{
UITextField* theTextField = ((UITextField*)[alertView viewWithTag: 1]);

if(buttonIndex == 1)
{
    NSLog(@"Password=%@", theTextField.text);
}
[theTextField resignFirstResponder];

//[theTextField removeFromSuperview];  
//[theTextField release];
}

Select allOpen in new window

I've been told if I need to swap clickedButtonAtIndex in for the delegate method, this could solve the problem, but I've no idea how to do this.
