stack trace

Playing any video on www.youku.com crashes QtWebkit 2.2 (Apple/Webkit 534.34) shipped with Qt 4.8.0 RC. An example link is provided here: http://v.youku.com/v_show/id_XMzQwNDczODQw.html . But this link might expire after a couple of months. Just play any other video on youku.com will crash it as well. 

All the videos plays well in QT 4.7.4 or earlier. 

>From what I can tell in the stack trace, it has something to do with the mime sniffer introduced in QT 4.8. I've attached the stack trace if it is any ehlp.
