Issue with dismissModalViewController

Question

I've got a problem when i dismiss a modal view:

I've got a tabBar with five tabs. I'm on the fourth tab and i display a modal view. When i dismiss it. I go on the first tab but i would like to stay on the fourth.

To show the modal I call this method, in the parent controller:

[self presentModalViewController:controller animated:YES];

To hide the modal I call this method, in the parent controller:

[self dismissModalViewControllerAnimated:YES];

I already try to call self.tabBarController/self.navigationController methods instead of self method but it's the same issue.

Someone has an idea?

EDIT:

I call the methods in the fourth tab's controller.

This is the context:

- (void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex {
    UIImagePickerController *imgPicker = [[UIImagePickerController alloc] init];
    imgPicker.allowsEditing = NO;
    imgPicker.delegate = self;
    switch (buttonIndex) {
        case 0: {
            [[NSUserDefaults standardUserDefaults] setBool:YES forKey:kMobiglissFromPicker];
            imgPicker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
            [self presentModalViewController:imgPicker animated:YES];
            break;
        }
        case 1: {
            if ([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera]) {
                [[NSUserDefaults standardUserDefaults] setBool:YES forKey:kMobiglissFromPicker];
                imgPicker.sourceType = UIImagePickerControllerSourceTypeCamera;
                [self presentModalViewController:imgPicker animated:YES];
            }               
            break;
        }
    }
}

- (void)imagePickerController:(UIImagePickerController *)imgPicker didFinishPickingMediaWithInfo:(NSDictionary *)info {
    UIImage *origin = [info objectForKey:@"UIImagePickerControllerOriginalImage"];

    UIImage *photo = [origin thumbnailImage:280
                          transparentBorder:0.0
                               cornerRadius:0.0
                       interpolationQuality:kCGInterpolationHigh];

    [icon replaceImageWithImage:photo];

    [serverProxy updateProfileAvatar:photo];
    [self dismissModalViewControllerAnimated:YES];
    imgPicker.delegate = nil;
}

- (IBAction)editAvatar:(id)sender {
    NSString *camera = [UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera] ? [WPLanguage get:@"SignupPhotosheetCamera"] : nil;
    UIActionSheet *photoSheet = [[UIActionSheet alloc] initWithTitle:[WPLanguage get:@"SignupPhotosheetTitle"]
                                                            delegate:self 
                                                   cancelButtonTitle:[WPLanguage get:@"CANCEL"] 
                                              destructiveButtonTitle:nil 
                                                   otherButtonTitles:[WPLanguage get:@"SignupPhotosheetGallery"], camera, nil];
    [photoSheet showInView:self.view];
}

Just a guess (you need to add more details): Does your viewController, which implements the UITabBarDelegate, set the selected item on viewWillAppear: (or one of the other methods called?
