    Description

      Steps to reproduce:

      1. Open a session.
      2. Copy a QML snippet from somewhere (e.g. https://bugreports.qt.io/browse/QTBUG-67145).
      3. Switch to another session where a Qt Quick application is open so that you can paste into its main.qml.
      4. Quickly paste the QML into main.qml and it will crash. This has to be done while the project is being read ('Reading project "qtdeclarative"' in my case), before it parses QML and C++ files.
