MFMailComposeViewController dismisses right away

Question

The situation is the MFMailComposeViewController was going to be presented. I saw it was presented half-way done, but then it got dismissed.

This is the error:

_serviceViewControllerReady:error: Error Domain=_UIViewServiceInterfaceErrorDomain Code=3 "The operation couldn’t be completed. (_UIViewServiceInterfaceErrorDomain error 3.)"

This is my source code to present the MFMailComposeViewController:

-(void) MailExecute {
    if ([MFMailComposeViewController canSendMail]) 
    {
        MFMailComposeViewController *mailViewController = [[MFMailComposeViewController alloc] init];   
        mailViewController.mailComposeDelegate = self;
        [mailViewController setSubject:NSLocalizedString(@"Check this new look", @"")];
        [mailViewController setMessageBody: @"my new look" isHTML:YES];

        [self presentModalViewController:mailViewController animated:YES];

        [mailViewController release];
    }
    else 
    {
        UIAlertView *alertInternal = [[UIAlertView alloc]
                                      initWithTitle: NSLocalizedString(@"Notification", @"")
                                      message: NSLocalizedString(@"You have not configured your e-mail client.", @"")
                                      delegate: nil
                                      cancelButtonTitle:NSLocalizedString(@"OK", @"")
                                      otherButtonTitles:nil];
        [alertInternal show];
        [alertInternal release];
    }
}

The weird point is that sometimes it happens, sometimes it doesn't. Please help me on this! I spend almost 1 working day to resolve this but no succeed.

This problem can occur when displaying a remote view controller -- a view controller run in another process -- as indicated by the UIViewService reference in the error message.

I've had this problem when displaying an SKStoreProductViewController, which is also a remote view controller. I'm not sure what the root cause is; the only thing that seemed to trigger it for me was presenting the view controller repeatedly.

For the SKStoreProductViewController I was able to check for this error in the completion block of the loadProductWithParameters:completionBlock: method. Does the MFMailComposeViewControllerDelegate give you a callback with an error about this? It may be that all you can do is listen for this error and show an error message to the user.

We should both probably file an apple radar about this.
