QskCombBox::openPopup creates a QskMenu, that has to be a top level item ( having the contentItem of the window as parentItem ). In situations, where the combo box has not been added to the scene it does not have a window and window()->contentItem() will crash.

To avoid the crash a simple check denying the call for this situation is good enough. However a user might expect, that the popup will be opened as soon as the combo box becomes visible. For this we would need to introduce some sort of flag, that indicates to do a delayed open.

For the moment you could overload QskComboBox::itemChange and do the setPopupOpen call there. Depending on your application you could also do a QTimer::singleShot to delay the opening.
