Hi,

Antonio, your workaround works here. Thanks a lot. Anyway I think the
current behavior is buggy. Even if I set the WA_DeleteOnClose flag on
the main window (which I expected to delete the main window and its
children when the window is closed) the script crashes if I don't
apply your workaround.
