Application: kontact (4.8.0)
KDE Platform Version: 4.8.00 (4.8.0
Qt Version: 4.7.4
Operating System: Linux 3.0.0-16-generic i686
Distribution: Ubuntu 11.10

-- Information about the crash:
- What I was doing when the application crashed: Nothing!
After an upgrade (kubuntu ppa, akregator 4:4.8.0a-0ubuntu1~oneiric1~ppa1), akregator crashes systematically after a few seconds. Maybe it has some problem in restoring some tabs that I had left opened with html pages and PDF files.

The crash can be reproduced every time.
