Ahhh I see... An item to put on the long term TODO list. ;)

Now I understand what you mean. Indeed there are many examples of how to trap 
mouse click events in a web page and show custom context menu:

http://developer.yahoo.com/yui/examples/menu/contextmenu.html
http://luke.breuer.com/tutorial/javascript-context-menu-tutorial.htm

And indeed webkit allows this where as khtml does not at least with the 
examples above. Anyhow, I currently do not see any option to disable this 
behavior in QtWebKit, namely in QWebSettings.
