    Description

      QComboBox crashes application after calling `clear()` and then re-add some items. 

      Minimal sample to reproduce it attached below. 

       

      However, I do find giving QComboBox a view, e.g. calling `setView(new QListView);` before adding items fix this problem.

      It doesn't, it reduces the chances of crash from 100% to 50% of the time. 

       

      Update: setView(new QListWidget) worked.
