I get a crash while scrolling page with debug build of Qt Demo Browser in Qt 5.0.2 and Qt 5.1.

Instructions to reproduce:
1. Open http://news.google.com/
2. Click the scrollbar on the right and drag up and down rapidly while the embedded YouTube flash video is loading
3. Refresh page
4. Repeat steps 2-3 until you get assertion failure

I have reproduced the issue using http://download.qt-project.org/official_releases/qt/5.0/5.0.2/qt-windows-opensource-5.0.2-msvc2010_32-x86-offline.exe. Debug output and stack trace below:
