QWebview fails to load page css on windows xp

[marwyn]

Hi.
I am currently trying to create a twitter sharing window in my application.
So I use the twitter api to get an url with an authentication token from twitter and load it in my QWebview.

The url looks like this: https://api.twitter.com/oauth/author...kWiFkc&lang=fr

There is no problem at all in windows 7, but in windows XP, the webview does not seem to load the web page's css...

So the result is very ugly (see attached images...)

Any idea to make this work ? Or any hint on why this does not work ?
