    GtkFileChooserNativeWin32: Uninitialize COM at end of thread
    
    GtkFileChooserNativeWin32 is created and shown on a secondary thread.
    This thread initializes COM support with CoInitializeEx but does not
    finalize it, so we have a leak. Fix that by calling CoUninitialize()
    before thread terminates.
