NSKeyedUnarchiver - Bad Access

I was trying to archive the object into a plist file and load it later to populate the tableView. The file seems to be zipped correctly, but I'm getting poor access when trying to get the value from the file.

Am I doing something wrong?

This is where I save it

// Create some phonebook entries and store in array
NSMutableArray *book = [[NSMutableArray alloc] init];
Phonebook *chris = [[Phonebook alloc] init];
chris.name = @"Christian Sandrini";
chris.phone = @"1234567";
chris.mail = @"christian.sandrini@example.com";
[book addObject:chris];
[chris release];

Phonebook *sacha = [[Phonebook alloc] init];
sacha.name = @"Sacha Dubois";
sacha.phone = @"079 777 777";
sacha.mail = @"info@yzx.com";
[book addObject:sacha];
[sacha  release];

Phonebook *steve = [[Phonebook alloc] init];
steve.name = @"Steve Solinger";
steve.phone = @"079 123 456";
steve.mail = @"steve.solinger@wuhu.com";
[book addObject:steve];
[steve release];

[NSKeyedArchiver archiveRootObject:book toFile:@"phonebook.plist"];

      

        
        
        
      

    

And here I am trying to extract it from a file and store it back into an array

- (void)viewDidLoad {
    // Load Phone Book
    NSArray *arr = [NSKeyedUnarchiver unarchiveObjectWithFile:@"phonebook.plist"];

    self.list = arr;

    [arr release];
    [super viewDidLoad];
}

      

        
        
        
      

    

The part where I am trying to create a cell

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    static NSString *PhoneBookCellIdentifier = @"PhoneBookCellIdentifier";

    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:PhoneBookCellIdentifier];

    if ( cell == nil )
    {
        cell = [[[UITableViewCell alloc] initWithFrame:CGRectZero reuseIdentifier:PhoneBookCellIdentifier] autorelease];
    }

    NSUInteger row = [indexPath row];
    Phonebook *book = [self.list objectAtIndex:row];
    cell.textLabel.text = book.name;   
    cell.accessoryType = UITableViewCellAccessoryDetailDisclosureButton;

    return cell;
}

      

        
        
        
      

    

Here's a bad access error
