      Description

      When a messagebox appears after closing a mainwindow after dismissing a messagebox then it can cause a crash.

      With the attached example, do the following:

      • Start the application and dismiss the initial messagebox.
      • Make sure the window is big enough to contain a whole messagebox
      • Type something and then click on the red X to close the window
      • Choose Don't Save
      • Go to File | New

      then it will crash right away.
