Crash on MFMailComposeViewController

if ([MFMailComposeViewController canSendMail]) {

    MFMailComposeViewController *mailViewController = [[MFMailComposeViewController alloc] init];
    mailViewController.mailComposeDelegate = self;
    [mailViewController setSubject:@"Support Enquiry"];
    [mailViewController setToRecipients:[NSArray arrayWithObject:EMAIL_SUPPORT]];

    [self presentModalViewController:mailViewController animated:YES];
    [mailViewController release];
}

My code breaks into

MFMailComposeViewController *mailViewController = [[MFMailComposeViewController alloc] init]; 

line with:

Any idea what is going on?

EDIT: the whole answer so far has done nothing, it still crashes :(

EDIT 2: I finally figured out the problem - I added a category to the text box, and MFMailComposeViewController didn't like it at all.

As reported by the questionnaire, it MFMailComposeViewControlleruses some of its own elements that should not be classified. So, you must be sure that there are no categories for elements such as UITextFieldor UITextView.

I had the same issue when presenting a view controller on iOS5 / 6 with ARC. My solution was to save an object representing MFMailComposeViewController with ivar.

@interface MyClass (){
     MailUtils *_mailUtils;
}
@end


{...
_mailUtils = [[MailUtils alloc] init];
[_mailUtils publish]; //in this method I create the MFMailComposeViewController
}
