The crash is because you're calling a method that doesn't exist, not because your variables are not initialized.

-setRootViewController doesn't exist prior to iOS 4.0. Use 

[self.window addSubview:self.tabBarController.view];

instead.

Or, update your target platfor to 4.0.2 or later. It's probably less than 5% of users that aren't using iOS 4 at this point.

This may show you the right direction. Let me know if the problem still continues.

Due to executing on different versions of iOS, that method may have deprecated.
