I wasn't able to reproduce this on my machine, but from the description it
sounds like it is only failing intermittently for you? In any case, Row should
always relayout when a child is destroyed (though note that the QML destroy()
calls deleteLater() than than deleting immediately); if it doesn't then yes it
is a bug.
