Hello:

  I'm using Debian sid which currently deploys Qt 4.8.0, QtWebKit 2.2.1, KDE 4.7.4. I use konqueror with webkit kpart as browser. When I have an opened konqueror session for maybe 2 or more hibernate/resume cycles (after been offline) konqueror will crash with the following backtrace:

This is my first webkit reported bug, so maybe this one is lacking information. Feel free to request any information needed to debug the problem.

Thanks and regards,
