Page for crash QWebKit

When scroll style is used (::-webkit-scrollbar*) closing page crash QWebKit.

Qt 4.5.3 / MSVC-2008

Crash always:
1. Open attached page in QWebKit (by load() or by setHtml())
2. Close page (by delete qwebkit or setHtml(""))

You can use qtdemos and HTML Previewer:
1. Paste attached page
2. Preview
3. Clear
3. Preview (crash)

Please follow the QtWebKit bug reporting guidelines when reporting bugs.

See http://trac.webkit.org/wiki/QtWebKitBugs

Specifically:

  - The 'QtWebKit' component should only be used for bugs/features in the
    public QtWebKit API layer, not to signify that the bug is specific to
    the Qt port of WebKit

      http://trac.webkit.org/wiki/QtWebKitBugs#Component

  - Add the keyword 'Qt' to signal that it's a Qt-related bug

Reproduced the crash on Linux with 4.5, but in no longer crashes with 4.6(.3).
Don't know if it was fixed already in previous 4.6 releases.

This cannot be replicated in WebKit 534.9, on Windows 7.

Tested r80013 on Linux and r80002 on Snow Leopard and have not been able to reproduce.

Should we close this bug?
