UIViewControllerHierarchyInconsistency exception when toggling autoCompleteTableAppearsAsKeyboardAccessory

[la-urre]

When changing the autoCompleteTableAppearsAsKeyboardAccessory property to YES, then later to NO, I get the following exception :

'UIViewControllerHierarchyInconsistency', reason: 'child view controller:UICompatibilityInputViewController@dd063de0 should have parent view controller:(null) but actual parent is:UIInputWindowController@db090000'

With the following stack :

I know this is not a very common use case, but I would like at least a workaround. I tried to call [self.autoCompleteTableView removeFromSuperview]; in several places, with no success. Anyone has a clue ?
