I have never tried silverlight with QtWebKit. I assume it is has a standard 
NPAPI plugin, but it might need some specific quirks just like most major 
plugins does.

A good place to start is Source/WebCore/plugins/win/PluginPackageWin.cpp where 
quirks are set for specific NPAPI plugins. Apparently it already have a 
blacklist of old versions of silverlight, and one quirk to not unload. That 
indicates it has been working at some point in the past, but probably just 
need updating to newer versions of the plugin.

Note that debugging these things is hard, you might want to check some 
chromium code and see if they have some quirks enabled and try to enable 
similar stuff in webkit.
