Crash when navigating through views

Hello I have in my app a modal view controller which when a certain button is pressed disappears and a view with a UITableView in it slides into position using a navigation controller. The porblem is when I press that button the modal view controller does disapear but instead of navigating to the next view the app crashes and I get the following stack:

#0  0x01387a63 in objc_msgSend

What is wrong with the app? Thanks

it is happing due to the timing of both events... you can do one thing first dismiss the model view and after that using timer navigate to next view after approx. 3 seconds... like this...

[self.navigationController dismissModalViewControllerAnimated:YES];

[self performSelector:@selector(moveOn) withObject:nil afterDelay:3.5];


-(void)moveOn

{

    SecondView *secondView = [[SecondView alloc] initWithNibName:@"" bundle:nil];
    [self.navigationController pushViewController:secondView animated:YES];
    [secondView release];

}
