Description Jocelyn Turcotte 2010-07-01 03:11:56 PDT 
To reproduce:
- Open a page with combo boxes and click one of them (like http://www.google.com/advanced_search )
- Get the QWebView destroyed (either by closing the tab in Arora or by switching to graphics web view in QtTestBrowser)
- Wander around browsing waiting for the cache to get cleaned (might take something between 1 and 5 minutes)

What happens is that when we show the combo box popup, we set the QWebView as the QComboBox parent.
If the QComboBox gets destroyed because of its parent getting destroyed, the reference in the render tree become dangling.
