meaning that the returned Application is not referenced, and can be double-freed

specifically, if I'm right, it IS double-freed, plus you try to use it after the 1st free:

• you instantiate an unnamed RefPtr<Application> from get_default()
• it immediately gets destroyed and decrements the reference count
• which, because it didn't increment upon construction, causes the Application to get destroyed
• then, on closing the window, it calls something on the Application to say 'one of your windows is gone', but there IS no Application!
• boom.
