Nil out the delegate of the profile name field in the edit current session prefs panel because it gets made first responder from a delayed perform after its delegate is released (the delayed perform is in openToProfileWithGuid:selectGeneralTab:). When the text field tries to become first responder it checks with its delegate, and that dies when zombies are enabled.
