UITableViewController back button must be pressed twice?

Question

Hey all,

i simple open a UITableView with

[self.navigationController pushViewController:memberView animated:YES];

The View opens correctly, but if i press the back button only the text changed from "Back" to "Profile" which is the Title of my originally view, another button click navigates back as expected.

It seems to me that the memberView is pushed twice on the view stack, how could this happen?
