popToViewControllerAnimated does not animate since ios5

Question

as topic describes, calling popToRootViewControllerAnimated / popToViewControllerAnimated does not do any animation anymore.

the code I use, which works fine with 4.x, is simply

[self.navigationController popViewControllerAnimated:YES];

so nothing special here. I just noticed, that for all my apps, running on iOS5, pop-animations have been gone. push-animations however DO appear.

now i wonder what to search for, if there is the need to define the transition/style of that animation?

Any help welcome, thanks!

Okay, calling "[super viewWillAppear]" in "viewWillDisappear" is sort of ... my bad!
