      Description

      If you want to compare a default constructed QJsonDocument to one that contains a QJsonObject, it will crash.

          QJsonDocument doc1;
          QJsonDocument doc2;
          const bool iseq1 = doc1 == doc2; // no crash here
      
          QJsonObject obj;
          doc1.setObject(obj);
          const bool iseq2 = doc1 == doc2; // here it crashes
      

      If we are comparing them the other way, it is working fine.
      I suspect that in operator==, only this is checked for null, but the right-side argument is not.
