[PyQt] Completely removing items from a layout

I wrote about this a couple of weeks ago, but I did not have a small working example to show the problem I'm having. Now I do. I have a layout created in Qt4 Designer which I fill with a series of complex layouts at runtime. That works great. Later on, I want to completely remove all of them and
