youtube full screen

I am using Qt's QWebView to Browse Youtube.
It can play youtube video,but when I press the full screen button the application crashed.
Is It a Bug?

N900 PR1.2

If something crashes, then it's definitely a bug. The question what is root cause for this bug.

I was able to reproduce the crash.

I observed that playing YouTube video with fullscreen size is ok via Maemo's Browser (Mozilla/5.0 (X11; U; Linux armv7l; de-DE; rv:1.9.2a1pre) Gecko/20091127 Firefox/3.5 Maemo Browser 1.5.6 RX-51 N900).
However, if I create a Qt Application Project (select Qt Gui Application) that includes a QWebView widget and plays a YouTube video in the widget. Playing with normal screen size is ok
But when I press the fullscreen (i.e. running YouTube's flash in QWebView) button, the application was immediately kill by the OS (Maemo/N900 PR 1.2).

Therefore, I think Qt's QWebView (the WebKit browser) does not fully support the YouTube's flash.
Could you give me some hints to solve the problem?

Thanks.

According to a backtrace the problem is with flash plugin. It requires some investigations to find a workaround.
